Week 3: Simple Linear Regression
In this week’s lecture we will discuss the simple (bivariate) linear regression model. This will be our gateway into the topic of regression-type analyses.
Lecture Topics
- How to draw and fit a line
- Basic concepts and terminology of linear regression
- Demonstrating how to fit and assess a simple linear model
In-class Activities
This will be a theory-heavy lecture. That said, students may wish to follow along with my Week 3 code, which demonstrates how to produce all the figures and models in today’s lecture.
Pre-class Prep
Optional
The data I use to illustrate linear models in today’s class are taken from:
