I have a question about R, and will be very grateful for any help. I have two variables X and Y, and think that Y is related to X by a function of the form : Y = X^Z, where Z is < 1. However, I'm not sure how to find the best-fit equation to fit my data to a curve of this form using R. Have you any ideas?
