WebApr 13, 2024 · Multicollinearity occurs when two or more independent variables in a regression model are highly correlated, leading to issues in interpreting the individual effects of the variables. It can result in unstable coefficients, inflated standard errors, and difficulty in identifying the true predictors. WebIn statistics, the variance inflation factor (VIF) is the ratio of the variance of estimating some parameter in a model that includes multiple other terms (parameters) by the variance of a …
