Dear All:

I want to obtain the box cox power of a variable I am working with. I
went via 'proc transreg' but I think that is not the right route
because my intent is to obtain lambda(conv or best) from a univariate
analysis.

Here my transreg route:

proc transreg data=boxcox ;
model boxcox(x / lambda=-2 to 2 by 0.25) = identity(y);

Does anybody know who I can obtain lambda 'unvariately' for a variable
x rather than modeling against y ?

Thanks,
