Learn how to use R to implement linear lt, one of the most common statistical modeling approaches in data science. Linear regression is commonly used to quantify the relationship between two or more variables. It is also ie to adjust for confounding. This course, part ofour Professional Certificate Program in Data Sciencecovers how to implement linear regression and adjust for confounding in practice using R. In data science applications, it is very common to be interested in the relationship between two or more variables.

The motivating case study we examine in this course relates to the data-driven approach used to construct baseball teams described in Moneyball. We will try to determine which measured outcomes best predict baseball runs by using linear regression. We will also examine confounding, where extraneous variables affect the relationship between two or more other variables, leading to spurious associations.

Linear regression is what is linear regression and why is it used powerful technique for shat confounders, but it is not a magical process. It is essential to understand when it is appropriate to use, and this course will teach you when to apply this technique.
