DataTransformation (power)
Contributor II
Hello,
I feel a bit stupid asking this... After 2 years using RM.
I would like to perform a power transformation like yeo-johnson and I'm not finding an operator to do that.
Does it exist?
Regards

Hi @Oprick ,currently there is no operator for performing power transformations, at least that I'm aware of. In case of the simpler ones like Box-Cox or Yeo-Johnson, you could rebuild them with the expression parser in Generate Attributes operator. As it's a quite handy transformation, we have already planed to add to an upcoming release of the TimeSeries functionality.Best,David8

The quickest way is to use use Execute Python and sklearn. It is part of sklearn preprocessing.

I currently use caret (R) and I perform this task with Execute R.
I just thought that somewhere in RM would exist an operator for this
Thanks you both for your very quick replies.
