Tips:
> If the distribution of predictors is very skewed or others rather than normal distribution, we
should do some reasonable transformation to make its distribution closer to normal distributio
n
> the transformation should be done before the normalization
> Dummy variables and label encoders do not need transformation
> Left skewed should be transferred into the right skewed by making values negative. And yo
u can apply log transformation to it.
> square root can be considered
