How to Calculate Variance Inflation Factor (VIF) in R

Witryna14 kwi 2024 · For the multicollinearity test, we used the correlation matrix and the Variance Inflation Factor (VIF) V I F = 1 1 − R 2, which shows the speed of the increase in an estimator’s variance when multicollinearity exists. It is obvious that, as the value of VIF increases, the problem of multicollinearity becomes greater. Witryna25 kwi 2024 · import numpy as np # variance of numeric features (df .select_dtypes (include=np.number) .var () .astype ('str')) Variances of numeric features (Figure: author) Here ‘bore’ has an extremely low variance, so this is an ideal candidate for elimination. WitrynaRetaining this outlier data during seasonal factor calculation would distort the computation of the seasonal portion of the time series data for motor fuel, so it was estimated and removed from the data prior to seasonal adjustment. Following that, seasonal factors were calculated based on this "prior adjusted" data. fit test anaemia
