Variable Inflation Factor Python. Mathematically the VIF for a regression model variable is equal to the. Int index of the exogenous variable in the columns of exog.
Int index of the exogenous variable in the columns of exog. It provides an index that measures how much the variance of an estimated regression coefficient is increased because of collinearity. Mathematically the VIF for a regression model variable is equal to the.
Therefore the variance inflation factor for the estimated coefficient Weight is by definition.
Variance inflation factor VIF is a measure of the amount of multicollinearity in a set of multiple regression variables. It provides an index that measures how much the variance of an estimated regression coefficient is increased because of collinearity. Mar 13 2020 Variation Inflation factor VIF. Variables that have variance inflation factor that is high ignoring the intercept and similar in value have a high chance of being collinear because they explain the same variance in the dataset.
