Hi all VFP gurus,

Has anyone a clue on the simplest way in calculate "least square" fitting from with VFP. The intention is pretty simple. A reasonable set of numeric (x,y) points available within VFP. We need the best fits for :
- a straight line,
- a logarithmic curve,
- an exponential curve.

As you imagine we do not want to use any VB stuff/dependancy. and are looking for the math formula not a visual representation. It could be straight VFP algorithms or dll-based library at a reasonable fee.

Any clue or any pointer welcome!
