nonlinear regression

How would I do a regression on a data set that follows a power curve? Also, a regression on a data set that follows a logarithmic scale? Thanks.

Hi,

there is currently no implementation of regression using a sum (or product?) of exponential basis functions available. What you can do is add the exp/log of everything and do standard polynomial/linear regression. This is in the end the same thing. The operator you might use for this is called Generate Function set.

Cheers,
Martin

Thank you for the quick response. Is there a thread that gives a tutorial on using polynomial regression? I have had issues when trying to model data with multiple independent variables.
