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.
