Description

Module 2, Lecture 4 Learning Outcomes: • Binary data: e.g. +/- • Binomial distribution (i.e. not normal) • Logistic regression suits Binary dependent data • Want probability of “success” • Model with logit link function (“transformed” probability) • Plot & interpret using probability of “success” equation • Today, great flexibility: o other statistical analyses for other data distributions
