Regression Episode 6: Categorical Predictors

Описание к видео Regression Episode 6: Categorical Predictors

Previous episodes on the linear regression model have all considered only continuous predictors. In this episode, Dan describes how categorical predictors can also be included in the linear regression model (aka general linear model)...

He shows how regression provides a model-based framework that subsumes many classical test procedures involving categorical predictors, including the two-sample t-test, one-way ANOVA model, and analysis of covariance model. It also, however, provides the flexibility to fit models that don't neatly fall into these procedures.
