WebNov 12, 2024 · First, we should produce a correlation matrix and calculate the VIF (variance inflation factor) values for each predictor variable. If we detect high correlation between predictor variables and high VIF values (some texts define a “high” VIF value as 5 while others use 10) then lasso regression is likely appropriate to use.

WebJun 12, 2024 · VIF is a number that determines whether a variable has multicollinearity or not. That number also represents how much a variable is inflated because of the linear dependence with other variables. The VIF value starts from 1, and it has no upper limit. If the number gets larger, it means the variable has huge multicollinearity on it. grandezza country club rentalsWebTwo of them have a correlation coefficient of around 0.8, which is rather high.
