Mutivariate Regression (GSL Topic: "Fitting")


I just started using GSL and wonder if it is possible to allow for a constant
in the multifit function?

The following would also be nice additions to the multifit function suite
(see MS Excel regression output for example):

1. Produce the correlation coefficient (r) and other statistics.
2. Allow fit variable weighting (not observation weighting).
3. Allow for principal factor computations.

Thanks for a great product!
