WebJan 29, 2024 · The variance inflation factor (VIF) identifies correlation between independent variables and the strength of that correlation. Statistical software calculates a VIF for each independent variable. VIFs … We can calculate k different VIFs (one for each Xi) in three steps: First we run an ordinary least square regression that has Xi as a function of all the other explanatory variables in the first equation. If i = 1, for example, equation would be where is a constant and e is the error term. Then, calculate the VIF factor for with the following formula : high fart
