Hi all, I have few doubts, While normalizing(min-max) on the dataset for regression,
- Should we apply normalization on the whole dataset or just on the train alone?
- Should we normalize the target variable also?
- Should we normalize the target variable and predictor variable in both the train and test set?
- if applying power transform, should we apply it on both predictor and target variable, should it be applied on both train and test set?
