Nonlinear ANCOVA?

I'm trying to do a non-linear analysis of covariance (ancova) and can't figure out how to do it with SAS or if it's even possible. Can anyone help me with this issue?

Specifically, I'm trying to test if the difference between multiple non-linear curves is statistically significant. The non-linear curves are in the form of y=aX^b. Additionally, I would also like to test the significance of multiple Explanatory variables on the response variable.

Thanks for any help!

Seems like you want to look at the NLIN or NLMIXED procedures.
