# New Tutorial on Linear Model Selection

21 Apr 2017It is often the case that some or many of the variables used in a multiple regression model are in fact *not* associated with the response variable. Including such irrelevant variables leads to unnecessary complexity in the resulting model. Unfortunately, manually filtering through and comparing regression models can be tedious. Luckily, several approaches exist for automatically performing feature selection or variable selection — that is, for identifying those variables that result in superior regression results. This latest tutorial covers a traditional approach known as *linear model selection*.
