Independent variables are collinear
WebIf two or more independent variables have an exact linear relationship between them then we have perfect multicollinearity. Examples: including the same information twice (weight … WebMulticollinearity happens when independent variables in the regression model are highly correlated to each other. It makes it hard to interpret of model and also creates an overfitting problem. It is a common assumption that people test before selecting the variables into the regression model.
