st: Yeo-Johnson Power Transformation

[Rajiv Sabherwal <sabherwal@umsl.edu>]

How can I perform Yeo-Johnson Power transformation in STATA? It is  
similar to Box-Cox transformation, but can be used with negative  
variables as well, unlike Box-Cox transformation which can only be  
used for positive variables. Please see  www.stat.umn.edu/arc/ 
yjpower.pdf and rweb.stat.umn.edu/R/library/alr3/html/powtran.html.

My dependent variable is a percentage that varies from -100 to +100,  
and hence Box-Cox transformation would be inappropriate, but Yeo- 
Johnson Power transformation would be perfect.

Thanks for your help.

Best wishes,

Rajiv
