Defines derivatives of a function.
The type describes the procedure for calculating the derivatives of a regression function TRegressFun with respect to the regression parameters (B array), evaluated at (X,Y).
Examples
csharp
private void SimplexParabolaDeriv(Dew.Stats.TRegresFun RegressFun, double x, double y,
TVec Pars, TVec Grad);
{
Grad.Values[0] = x*x;
Grad.Values[1] = x;
Grad.Values[2] = 1.0;
