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.

Very practical/hands-on intro to regression models. You will definitely be able to apply those methods after this course whenever you need them.

This course is packed with great lessons and Prof. Caffo puts it all together very cogently.

Data, our “raw” material, becomes plentiful. Let’s learn form it.

Thanks to constant progress in information technologies, this increasing production of data is an outstanding opportunity to improve our knowledge of subject matters we care about, e.g. environment, health, markets…

Properly analyzing these data in the scope of addressing specific questions is not trivial. But it can be learn. And if there were one place where one could acquire these skills and become anxious to grow in that field, this would be the Coursera Regression Models course. Data analysts, like any professionals, need her/his set of tools. Good tools make good patricians. The Coursera Data Science Specialization that includes this Regression Models class is where one can learn how to use the right tools and reduce them into practice. Passionate instructors who obviously take great care in communicating effectively the knowledge they master teach these courses admirably. Highly recommended course and specialization,

There are so many unanswered questions, so many new relationships to uncover. Learn how.

I loved studying Regression Models taught by Prof. Brian Caffo. I think these are very important techniques that I will be able to use for my research and analysis.

I found the teaching to be very in depth in explaining various aspects of regression model development.

Love the whole course approach on the importance of linear models and how one should interpret them to get a better grasp of the data one possesses - one should definitely take the statistical inference course before attempting this course beforehand.

I learned a lot through this course! It's not easy, and there's a lot of technical details that required me to watch the videos 2-3 times through to have a proper grasp, but super helpful stuff!

My name is Jose Antonio from Brazil. I am looking for a new Data Scientist career (https://www.linkedin.com/in/joseantonio11)

I did this course to get new knowledge about Data Science and better understand the technology and your practical applications.

The course was excellent and the classes well taught by teachers.

Congratulations to Coursera team and Instructors

With the first few videos, I was concerned I would be re-living the nightmare that was the Statistical Inference course. (I gave a long review of that one. To summarize Statistical Inference: I hated it. But I learned things. Those things stuck. I used them in real life. That's good.)

But wow, after getting through this course, I loved it. Very practical and useful stuff. It had me thirsting for more information and I found myself reading unassigned material. I became particularly interested in Anova and continuing to read up on it even though I am done the course.

I would take this course again. I would recommend it to those wanting to learn more about data science. It's got some quirks and room for improvement, but overall it's a good course.

Perfect course toward the data science specialization. It gives good understanding and improve my knowledge of inference statistic. I have the opportunity to explore all the plotting concept and apply them in regression models arena.Good to take this course to step in the concept of machine learning.
