WebOct 4, 2024 · Linear regression is used to quantify the relationship between a predictor variable and a response variable. Whenever we perform linear regression, we want to know if there is a statistically significant relationship between the predictor variable and the response variable. We test for significance by performing a t-test for the regression slope. WebThis process is applied until all features in the dataset are exhausted. The goal of RFE is to select # features by recursively considering smaller and smaller sets of features rfe = RFE (lr, 13 ) rfe = rfe.fit (x_train,y_train) #print rfe.support_ #An index that selects the retained features from a feature vector.
