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.

Probably the most conceptually challenging and practically useful course in the JH data science certification series (so far... I have a few more courses to complete).

This time the professor Brian Caffo was more helpfull, explained better the concepts, and sometimes repeated some of the most important information... Good course!

Good course for basic regression. Would have enjoyed more time spent on properly interpreting results and how they are relevant to answering business questions.

Nice course that helps make your foundations in regression modelling strong. The complexity of the course project can be increased to a more difficult level.

This course is a practical introduction to the regression models. Materials and organization are great, however slides and presentations require some work.

Good course. My only negative remark is that I really missed the swirl exercises that were available for the other courses of this specialization.

Great course to learn various regression models and "R" tools to implement them efficiently, but

was little hard to keep with the deadline.

Some lab work (swirl()) did not match the material presentation order. Essential coursework delivered at a blistering pace. Good Stuff.

Great course, learned a lot. The only point is that I was hoping to learn more about general linear models and its applications.

Great introduction to regression models. A ton packed into the class. Be ready to be challenged, but you'll learn a lot.

Useful information about regression models, but to really understand the math you have to do a lot of googling yourself.

Would love to see more hands on practical explanations rather tan mostly slides.

Content is great though!

This a challenging course, overall I think it was good, but the material could be a bit better presented.

Really good! All the pieces from the previous courses start to come together into a whole.

Videos were very difficult to follow along with. Overall, I learned a good amount though.

Nice course. It would however be better to include a summary how to approach an analysis.

Good introduction to regressions and the process of applying regression analysis to data.

The content is to long, maybe would be interesting split the content in other modules.

Great course, but please check those subtitles that are occasionally completely off!

Very good material but often too fragmentend/messy. The notes would need re-writing.

It is a great introductory course into Regression analysis. I highly recommend it!

Quite practical. It does encourage one to follow-up with a more advanced course.

Overall a good course. But I was expecting more in depth covering of the topics.
