I have a few Independent variables that's normal and a Dependent variables that's skewed , I pick log(feature+SHIFT) to correct skewness. The procedure I follow to get prediction is just take exp(predictions)-SHIFT.
Now how do I get my predictions for the following cases.
1) I have Normal - dependent variable and the independent variables are skewed , I transform only a few of them using same log(feature+SHIFT) where the shifts are unique for every feature.
2) Transformations on both dependent and independent variables with different SHIFT values.
Suitable code examples will be highly appreciated. Thanks
