VIF test should be used for the independent variables only!!!. I get this comment from the reviewer ... what does that means?

29 March 2024 1 8K Report

My research simply contains one independent variable with two sub-variables and one dependent variable, and I only counted the VIF for the main independent variable ?!!

Dr Amit Kumar

VIF measures the extent to which the variance of an estimated regression coefficient is inflated due to multicollinearity among the predictor variables. The dependent variable is not subject to multicollinearity because it is not influenced by other variables in the model. Therefore, VIF is not calculated for the dependent variable.
