课程概述

This course covers the essential exploratory techniques for summarizing data. These techniques are typically applied before formal modeling commences and can help inform the development of more complex statistical models. Exploratory techniques are also important for eliminating or sharpening potential hypotheses about the world that can be addressed by the data. We will cover in detail the plotting systems in R as well as some of the basic principles of constructing data graphics. We will also cover some of the common multivariate statistical techniques used to visualize high-dimensional data....

Very good course! It provide me the foundation in learning how to plot and interpret data. This will definitely strengthen my "R programming" to generate publication type figure for my genomics data!

This is the second course I have taken from Roger Peng and both were outstanding. I have a strong math background, but not much of a background in stats, but this course was very approachable for me.

Great lecture. I hope there were more assignments. (1 per a week maybe).

I learned many statistical concepts and rcodes by taking this course.

Thank you:)

Course material, lectures, exercises are excellent.

There was not enough theory, and there was too much specific to R and graphing packages covered.

The course was fantastic. It was very challenging. I could do with some additional opportunities for exploratory analysis to reinforce some concepts.

Good course on plotting libraries and useful plots in R. Wished there was more coverage of ggplot and less on lattice, but overall a useful course.

though presentation was good ,felt it should have been better in small sessions , lost interest half way through , continued later to complete

It delves into many important topics. I would advice to explore the topics in much more depth on your own. Overall a good breadth of topics.

The course is useful with a lot of learning.

The second half needs more of improvement, I think the pace is quite fast compared to others.

Awesome course ! It reaches you the crux of exploration of data . Although the SVD section could have been more thorough and detailed.

Great introduction! I am eagerly awaiting the opportunity to apply clustering and dimension reduction on real data in future courses.

Very interesting and insightful course. I enjoyed it.

Assignment was okay, could have provided more challenge and depth though.

Very good course. I liked the clustering examples. They were a little bit detached from the rest, but they were also great.

great intro to the plotting system. could be better with a dimension reduction assignment or quiz. this is very important!

I would rate 5 if the course wasn´t so focused on graphic analysis. But, even Like that it´s a very good experience.

It was a lot of material in a short time frame, but I feel like I really have a good grasp of creating graphs in R.

More practical exercises using ggplot2 and clustering would be beneficial. Maybe need to be a 8 weeks module.

Quantitatively assignments were less with no assignment for Week 3, however, the swirl exercises were good

this course is more about creating chart for EDA, need more material for reading/interpreting the charts

Useful for learning how to make plots, but not too detailed. Further analysis would have been helpful.

Really good if you do not have any background in the field. But even if you do it is a great review

Some of the links in the lectures are out of date, the forums usually have an updated link though.
