[net.wanted] Wanted: program for particular least squares problem

derek@uqpsych.OZ (Derek Austin) (08/06/84)

A colleague of mine is modelling (human) memory operation and  is
after  a program that will calculate least-squares best fit for a
data set given:

        a.  A particular function
        b.  Constraints for function coefficients

I    understand    that    something    called    the    "Steppit
technique/algorithm"  is an example of something would do the job
nicely.

Can anyone out there come to  his  assistance  with  a  piece  of
public or private domain software?

Thanks in advance,
