Witryna9 maj 2024 · The most common way to detect multicollinearity is by using the variance inflation factor (VIF), which measures the correlation and strength of correlation between the predictor variables in a regression model. The value for VIF starts at 1 and has no upper limit. A general rule of thumb for interpreting VIFs is as follows: 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.
