Week 3: Simple Linear Regression

January 22-23, 2018

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.

*Note: We actually did this lecture on Jan 24 in a makeup lecture

Lecture Topics

  • How to draw and fit a line
  • Basic concepts and terminology of linear regression
  • Demonstrating how to fit and assess a basic 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:

Huang et al. (2017), Sooty tern (Onychoprion fuscatus) survival, oil spills, shrimp fisheries, and hurricanes. PeerJ 5:e3287; DOI 10.7717/peerj.3287
