Derivatives of power function.
Unit
RegModels
Declaration
Procedure PowerDeriv(RegressFun: TRegressFun; X, Y: TSample; const Pars: array of TSample; Grad: TVec);
Description
Calculates the derivatives of the power function at point (X,Y) with respect to the regression parameters Pars. The results are returned in Grad vector. Grad.Values[I] contains the derivative with respect to the I-th parameter. The Length and Complex properties of the Grad vector are adjusted automatically.
