Hi all,
I'm trying to plot and fit data to a power function (y=ax^b) using proc gplot. The interpol option in the symbol statement allows you to define a type of regression (eg: rl=linear, rq=quadratic etc) but I don't see the power function as being one of them.
Is there perhaps another way to do this? I can easily do this in Excel as the trendline option has the power option........but need to use SAS to do it.
Thanks!
Mike
Do you have some sample data you could post up?
