Dears,
I'm analysing a trait expressing in decimal between 0 to 1 without normal distribution.
I want use Box-Cox transformation,
In SAS using PROC TRANSREG, I want to find the best value for LAMBDA,
but with observation equal to zero in my variable it faces to problem which I think due to the "log(0)".
What can I do for this problem?
many thanks.
