Hi,
I'm using the package gnm to perform non-linear models and I cannot
find how to write the formula for a power function model. I found out
that there was a function Raise() to do this but it no longer exists
in the package. I guess I need to use the nonlin function Mult(), but
I couldn't find how.
The equation is something like (1) y ~ A * x^B or (2) y ~ A *
B^x.
Thank you for your help,
Best regards,
Natalia
