Hello,

I am a non mathematician so this question may seem a little

simplistic, but I hope someone can help.

I have been looking for some Fortran code for multiple

polynomial least squares regression. I have data in an

x,y,z format and I want to obtain residuals for each

data point from trends of 1st, 2nd or 3rd order

polynomials. There seems to be a vast amount of code

for regression but I haven't been able to find any for

straightforward multiple polynomial regression. I need

code in Fortran as I want to call it from existing

Fortran 77 code. Any suggestions as to where I might find

Fortran code for this purpose would be greatly

appreciated.

Thanks in advance.
