  • "Professor Babinec did a wonderful job of leading us through this material.  It is obvious that he has a passion for this subject.  His breadth of knowledge of and experience with cluster analysis added significantly to the course.  He gave very helpful answers in the discussion forum!  Anuja, our teaching assistant, was very supportive throughout the course as well.  The course material was challenging but fulfilling, helping us appreciate the subtleties of cluster analysis rather than thoughtlessly plunge ahead.  In summary, this was a very satisfying and useful course."

    -- William Barbour, Audi of America through Modis
  • I am working for Scotiabank/International Banking-Marketing (Toronto-Canada). Since we are manipulating tons of data at the customer level for more than 27 countries, R would be the perfect complement tool (we have been using SAS) for customer analytics. I am new on this R world but I would like to apply it on a daily basis soon.

    -- Raul Bauza, International Banking at Scotiabank

  • The tools and understanding gained in this course are absolutely vital to the practice of data analytics (at least to an acceptable standard)... Thank you for a great course. I have learned an incredible amount

    -- Timothy Berlyn, Holland America Group
  • I felt this course helped me "unwrap" another layer of R,  It helped me become a little more comfortable, and less afraid of writing an R program.

    -- Douglas Mayfield, Holland America Group
  • I found this course to be very helpful. It wasn't like other courses where you just run example code and change a few things here and there.  I learned a lot and have even applied what I've learned in this course to the other course I'm enrolled in currently.... Thank you for the great notes and text!

    -- Sofia Auer, Canada Border Services Agency
  • The course helped me learn Tableau and some of the effective Visualization techniques. I really liked the detailed assignments with hints and steps required to perform some of the tasks.

    -- Ramesh Paskarathas, Canada Border Services Agency

    -- Jim Pearse, Director, Health Policy Analysis
  • Every professor has unique and great qualities in them and the unique and great quality that I found in Prof Anthony Babinec is that he can write pages of explanation for each and every line in the book... He is an awesome professor. He explained each and every doubts we had to the perfection.

    -- Vinuth Tulasi, Juniper Networks
  • I feel this class gave me a much better understanding of how to design experiments and enhanced my statistical vocabulary. One thing I liked about Mr. Babinec's approach was that his written explanations were precise. Once I read and comprehended them, they really helped break down what I was reading in the text that was more understandable, especially by comparing/contrasting terms. Overall, I enjoyed the class and it was well worth the time spent.

    -- Bryan LeRette, Senior Market Research Analyst - Strategy & Planning, Mosaic Life Care
  • Instructor John Verzani provided timely and detailed responses to each and every question posted on the forum. His depth of knowledge in both statistics and R and his passion for teaching are the major contribution to the success of this class!

    -- Ming Zhang, Senior Statistical Analyst, Northwestern Medicine
  • I took this class out of general curiosity and the fact that it used Python, which is increasingly attractive to me in building my own software tools.  To my delighted surprise I found the course to be one of the very best (out of more than 20) I have taken at Statistics.com.  It proved a harmonious blend of theory (buttressed by relevant reading and videos by the instructor), focused homework exercises, and training in Python coding.  As a result I learned much and enjoyed the process greatly.  I was particularly impressed with the instructor's choice of homework assignments, which fascinated me, and with the importance he placed in students writing clear, even elegant, Python code.  This is my fifth course using Python at Statistics.com and while I found the other courses quite useful to varying degrees, I never before had an instructor who spent time advising me on the fine details of my actual coding style and suggesting useful improvements.  Allan Leis is a seasoned professional, working in the field, and it was a luxury having him cast an experienced gaze on my rudimentary code.  It's the kind of thing that would never happen in a MOOC and shows the value of a course such as this.

    -- Milan Hejtmanek, Seoul National University
  • This course has been a life/work changer for me. Within 2 weeks of taking this class, I was able to produce far more informative plots than I ever had before. I'm inspired to take more classes and learn as much as I can about this wonderful new world. Regarding Statistics.com in general - based on my experience with this course that is, this is a class act online program. A friend recommended it several years ago, but I opted for free MOOCs instead, which haven't worked for me. The small size of the classes, the attention by the instructor, and the assignments bode well for learning. All in all - a great course!

    -- Susan Kamp, Senior Scientist at SM Stoller (U.S. Department of Energy)
  • It was perfect, much recommended to anybody wanting to understand the dynamics behind political microtargeting and how it can be applied to business. Many theoretical aspects that were known in the past have been empirically implemented with wonderful exercises of Mr. Ken Strasma.

    -- Karolis Urbonas, Amazon
  • I have never had an online class before, and I have typically heard bad things about them, so I was shocked when I found out just how easy this course was to manuever. I really liked the format - it allowed me to work at my own pace yet still check in with the teacher and the other students. A really great experience for my first online course.

    -- Kristin Powers, Amazon
  • Both the instructor and the teaching assistant were approachable, helpful, and knowledgeable about the subject matter, and provided constructive feedback about discussion board posts and assignment submissions.  The textbook will be a valuable resource for future projects.

    -- Dennis Fuster, Kremers Urban Pharmaceuticals

Her feedback, comments were so very valid and felt really blessed to meet and get taught from such wonderful people.  Every one at Statistics are such wonderful and nice people. I am really blessed to be part of such an institute :)

    -- Vinuth Tulasi, Juniper Networks
  • Both professor Verzani and the TA's were always ready to answer questions. This is probably the most actively I've ever participated in an online class. I really benefitted from this course and I appreciate all the thought and effort put into making it such a valuable resource for R users!

    -- Camille Payre, UCB Pharmaceuticals
  • Jen is an amazing instructor. She is open to discussions, knowledgeable and willing to discuss topics. Her you tube videos added substantially to to the course and understanding the material

    -- Vanessa Scherman, University of South Africa
  • The Video/ PPT lectures were excellent. Dr. Golbeck and the TA did a great job to ensure a very good environment to learn and obtain feedback. This course is a great addition to statistics.com

    -- Satish Rao, IBM
  • Brian Marx is the best teacher I have had. The homework was straight forward and Brian responded to questions on the discussion board in a timely fashion. Thank you Brian for all your effort.

    -- Suzette Blanchard, City of Hope National Medical Center
  • I thought the notes were fantastic - very clear, and interesting. One of the best courses I've ever taken!

    -- Sofia Auer, Canada Border Services Agency
  • I enjoyed this course very much. I was leery of the Excel plug-in, but it worked out well.  The study materials were well thought out and effective. The instructor took an active interest in our progress.  I would highly recommend this class.

    -- Edward Purcell, Mainline Information Systems
  • Very interesting course, excellent content.  I'm looking forward using these concepts in my business pretty soon

    -- Yannick Messiaux, AgieCharmilles Management SA
  • This class was very interesting and practical. I learned how to structure experiments to be able to isolate the effects that the input variables have on the response variable. It was also interesting seeing the application of linear regression analysis in a little different way than I experienced in the linear regression class I took just before this. I appreciated the text and will keep it for reference.

    -- Robert Wells, Director Business Intelligence' Adventist Healthcare
  • I would recommend this class to anybody (with a basis in probability theory and calculus) who wishes to get acquainted with bayesianism

    -- Jimmy Bourque, Université de Moncton
  • I learned a great deal from this course. I thought that the instructor, Dr. Congdon, prepared excellent lessons for the course.  Dr. Congdon's responses to the questions on the discussion board were clear and very helpful. The TA for this course was also excellent.

    -- Margaret Palmisano, Université de Moncton
  • I would contend that this Bayesian Computing class (and other Statistics.com classes I've taken) has extremely good value. I have gotten so much education for relatively little expense... the assistant teacher's feedback was extremely helpful.

    -- Richard Coshow, QDNR
  • This course was tough, but immensely satisfying.  The instructor's lecture notes were written very clearly and were easy to read

    -- Alisa Boehme, QDNR
  • A very nice introduction to Hadoop.  Extremely helpful and I appreciate all the work the instructor put into the course.  I actually benefitted from the lack of Java specific help since I had to generate code on my own... I wasn't able to ""copy / paste"" which is exactly the kind of environment I needed.  I was forced to dig in and found that very rewarding

    -- Jeff Crawford, Jackson National Life Insurance Company
  • I thought the course was well organized and I liked the selected readings and text by Stephen Few

    -- Susan Stachler, DePaul University
  • Visualizing data interactively will be useful when performing any type of data analysis. Dr. Shmueli always answered questions on the discussion forum quickly and very thoroughly.

    -- Jorge Medina, DePaul University
  • I am going to rock the graphics at work! This was an excellent intro to the multiple types of graphics in R, and how and when they can be combined (or not).  This can be very confusing, so this type of intro helps to avoid some of the pitfalls and dead ends. It was a fun and interesting class, with lots of opportunity to create graphics and learn new techniques.

    -- Lesley Painchaud, Scientist at US Navy
  • I will be working a lot creating customized plots and graphics for reports. This class was crucial for my understanding of graphics in R and how to fully customize the output. Thank you so much, this was truly an amazing course and helped out a lot. Well done!

    -- Josh Paulson, Investment Analytst, Claragh Mountain Investments LP
  • It helped me immediately with my job. I was able to understand and apply the concepts to a time-series analysis. The R package I was using (vars) required that I read the documentation, which used much of the terminology and concepts in this class. I would have been quite lost without that introduction to the material. This class really stretched my brain! I loved it!

    -- Lesley Painchaud, Scientist at US Navy
  • The TA was really helpful and very responsive to questions.  Overall the course was a great experience.

    -- Marilyn Wheatley, Minitab
  • The more courses I take at Statistics.com, the more appreciation I have for the smart approach, quality of instructors, assistants, admin and program. Well done and look forward to the continued evolution of this institution!

    -- Leonardo Nagata, Walmart eCommerce
  • I can't recommend this class highly enough.   Professor Shmueli is an excellent teacher and has written a very clear and practical book.  The professor provided good feedback to questions and introduced a wide range of fascinating supplemental information to the course for individuals who want to go deeper.   The TA was also excellent with good feedback on the homework

    -- John Riley, Walmart eCommerce
  • I really liked how the instructors coordinated the course. They are very friendly and very knowledgeable. I found their textbook Practical Spreadsheet Modelling an excellent resource

    -- Shadreck Mapfumo, IFC - International Finance Corporation
  • The modeling techniques learned in this course will greatly assist me in understanding the use of models in the banking industry.

    -- Stephen Zinder, FDIC
  • I am very appreciative of the instructor an the TA for their unflagged availability and contribution to this class. It was a very good class and I enjoyed it and would recommend others to take it.

    -- Etienne Nzabarushimana, University of Arkansas for Medical Science
  • The course was very interesting. It was the first time I've had this level of exposure to data mining. The real life examples and exercises covered during the course helped me to understand the various approaches and techniques presented. It was a terrific course

    -- Peter Mulready, System Architect at Boehringer Ingelheim Pharmaceutical
  • The theory was clear and well explained; which allowed me to tackle very unfamiliar concepts with relative ease. I feel I now have a really firm foundation on which to build and have been encouraged by this course to keep learning and working towards going even deeper into stats and analysis.

    -- Claire Kentler, La Trobe University
  • The [instructor] was exceptional at answering unclear issues raised and pointing you to right materials to further help your understanding

    -- Oluseun Shittu, West London Mental Health NHS Trust
  • This was a very good course.  Dr. Indrayan has put together a very good on-line learning package.

    -- Kathy Denesyk, Clinical Pharmacist, London Health Sciences Centre
  • Gave me some insights in designing experimental studies, analysis of such eg matched case controls studies, and survial analysis. The course was a master piece. I like the style and I will take more courses.

    -- Richard Chamboko, NOVA Information Management School
  • I really enjoyed this course and found it sufficiently challenging, although well explained and the instructor was very approachable and explained concepts and addressed questions clearly and fairly.  Looking forward to Biostats 2!

    -- Claire Kentler, La Trobe University
  • This was a highly interactive course with a first rank expert in his topic who, fortunately, was also good communicator who likes teaching

    -- John Steward, Welsh Cancer Intelligence & Surveillance Unit
  • This course is well designed and the course materials are simply awesome! The instructor is very knowledgeable in the field and has tons of examples with codes from his website, which is a huge benefit. The focus on programming and practical tips, as opposed to theoretical details, is also a great benefit.

    -- Victor Lo, Vice President, Data Science, Fidelity Investments
  • In a nutshell of the 13 Statistics.com courses I have completed to date, this is one of the top three in the intellectual excitement it generated, and the very best taught of all.  Prof. Sen has created a jewel of a class,packing an entire semester's work into 4 weeks, but doing so with such intelligence, panache, and elegance that I enjoyed every minute of the many hours I devoted to it.  His deft blending of video lectures, outside reading, sample programs, and personal feedback on homework was exemplary.  It would have taken me a whole year to learn this material on my own, if I could have done so at all.  I cannot praise this course highly enough

    -- Milan Hejtmanek, Seoul National University
  • This course will help me handle statistical analyses and related consultancy in a correct, professional and intelligent way.

    -- Alfred Keter, Biostatistician, USAID-AMPATH
  • I came into this course knowing the basics of what Structural Equation Modeling could do. I am leaving this course with a whole new understanding of the ways it can be used to answer many different types of research questions. From psychometrics to multi-level modeling, I now feel like I have a whole new bag of tricks in my tool-belt. While I have read books, being able to go through exercises and get feedback was critical. I do not believe I would have come to such an understanding on my own without this course. It was excellent.

    -- Brandi Hinnant-Crawford, Western Carolina University
  • I am only beginning to use SEM. Without the course I would have lacked the understanding and confidence to try and use SEM. I now feel confident that I could apply one of the models and use the results for work purposes and publication.

    -- Celeste Combrinck, Centre for Evaluation and Assessment
  • This is very good. The explanation is so clear and practical. The problems are very good. They are not too easy nor too difficult, and they are very practical. Those problems help me to apply the skills in the field

    -- Yonetaro Kawada, ABeam Consulting
  • Excellent format, with flexibility to work whenever time is available, and work a bit ahead as needed to work around other committments

    -- Michelle MacKinnon, SanDisk
  • I have to say that I learned more about statistics in one month with Statistics.com than I learned in a full quarter of engineering statistics as an undergrad 20 years ago. The resampling concept makes all the difference in the world. I now more fully understand what is behind the mathematical concepts they tried to teach me in college.
