Hi,
I've been fighting against the syntax of the option "Weights" in the
NonlinearRegress command. I want to fit large data sets and I don't want
to type hundreds of values. I'd rather use a function defining the weight
of each data points. But how to do it with Mathematica 3 for Unix?
For instance:
NonlinearRegress[dataset, fitfunction(x,para),{x},{para},Weights->{???}]
I would appreciate someone helping me remove the question marks!
