Effect of multicollinearity on regression

WebSep 27, 2024 · Collinearity can be a linear affiliation among explanatory variables. Two variables are perfectly collinear if there’s a particular linear relationship between them. Multicollinearity refers to a situation at some stage in which two or greater explanatory variables in the course of a multiple correlation model are pretty linearly related.
