Normalizing the data set
$begingroup$
I have two questions :
1) Why doesn't normalization have any effect on linear regressor performance (mathematical approach is appreciated ) ?
2) When we normalize the training set we ought to normalize the target set too . Won't it affect the performance ? I mean won't the data set change completely because the model had different Ranges of features as compared to the ranges of features in target set .
I tried googling the questions but was not able to come to conclusion . Any help would be appreciated .
Thanks !
