課程概述

Linear models, as their name implies, relates an outcome to a set of predictors of interest using linear assumptions. Regression models, a subset of linear models, are the most important statistical analysis tool in a data scientist’s toolkit. This course covers regression analysis, least squares and inference using regression models. Special cases of the regression model, ANOVA and ANCOVA will be covered as well. Analysis of residuals and variability will be investigated. The course will cover modern thinking on model selection and novel uses of regression models including scatterplot smoothing....

Excellent course that is jam-packed with useful material! It is quite challenging and gives a thorough grounding in how to approach the process of selecting a linear regression model for a data set.

It really helped me to have a better understanding of these Regression Models. However, I've noticed that there is a video recording repeated: Week 3, Model Selection. Part 3 is included in Part 2.

This course is better than Statistical Inference, and I think it is as useful. Non credit excersise are still very good at helping with understanding in practice what is going on.

Useful class, but the content often simple in nature was explained in a confusing/complicated way. But the material is important and there is purchase for taking the class

The material was a little disjointed and not always explained with examples. Passing this course required a significant amount of outside study and research.

This is a decent class, covering linear regression and a few of its variants in good detail. It's a challenging subject, but presented acceptably here.

Lots of material needs additional study (from different sources) as it's only summarily explained. Much math without the link to the praxis :-(

The content was exposed in a very confused manner. I did not like how the teacher explained. It seemed more difficult than it really is

Starting from the first week swirl practice, course content is poorly organized making even simple concept difficult to understand.

I find it very tough to understand everything. Buying the course book helps to overcome this. You have to dedicate a lot of time.

Lots of math, but it would be more productive to focus more on the output of R and better understand the results

Bad audio and video quality. Too fast on some complex ideas and too slow when come repetitions between videos...

I think this course needs more emphasis on practical applications and less mathematical background.

Very interesting course, yet course content could be spread more evenly (week 4 is really a lot)

Course has more theoretical concept than application.. It has to be more application based

I think a revamping of the concepts in a more ellabroate way is required in the course
