+## L14: Intro to Linear Regression ([pdf](../slides/14-regression-1.pdf), video)
+
+[![Lecture14-Regression-Intro](../assets/images/14-regression-1.jpeg)](../slides/14-regression-1.pdf)
+
+This is the first lecture in a series dedicated to regression modeling. We talked about simple / multiple linear regression and how standard errors can be used to perform hypothesis tests on the estimated coefficients, with many examples throughout.
+
+The importance of having a good understanding of linear regression before studying more complex statistical models cannot be overstated.

+### Lecture Readings
+
+
+> James, G., Witten, D., Hastie, T., & Tibshirani, R. (2013). [An introduction to statistical learning](https://www.academia.edu/download/60707896/An_Introduction_to_Statistical_Learning_with_Applications_in_R-Springer_201320190925-63943-2cqzhk.pdf) (Vol. 112, p. 18). Springer.
+
+Chapter 3 reviews some of the key ideas underlying the linear regression model, as well as the least squares approach that is most commonly used to fit this model.

+> Grolemund, G., & Wickham, H. (2018). [R for data science](https://r4ds.had.co.nz/index.html).
+
+This book will teach you how to do data science with R: You’ll learn how to get your data into R, get it into the most useful structure, transform it, visualise it, and model it. In this book, you will find a practicum of skills for data science. Just as a chemist learns how to clean test tubes and stock a lab, you’ll learn how to clean data and draw plots—and many other things besides. 
+
+Chapters 22-24 (Modeling) are the most relevant for this lecture.

+
+Chapter 4 covers regression modeling. Note the emphasis on prediction, instead of the more common goal of explanation in empirical research.

+
+Among others, the paper addresses a common false belief that the probability of a conclusion being in error can be calculated from the data in a single experiment without reference to external evidence or the plausibility of the underlying mechanism.

+
+Probably the most in-depth coverage of regression modeling possible. More emphasis on theory than other sources.
