[SciPy-Dev] Understanding scipy.stats.boxcox

[Keith Sloan]

I have the following questions about scipy.stats.boxcox and looking for 
pointers guidance.

I would like to implement something similar to boxcox but with the 
following differences.

1) I would like to use a different transformation function from w=(y^x - 
1) / x

2) I would separate from 1) like to have the target be other than a 
Normal/Gaussian distribution, I am thinking of a Plank function for a 
Blackbody

I had a quick look at 
https://github.com/scipy/scipy/blob/master/scipy/stats/_continuous_distns.py 
but was still lacking enlightenment, so would
welcome some pointers

Thanks
