Example

In the following example we generate some data. Then we fit multiple linear function to this data and retreive it's regression coefficients.

Uses MtxExpr, RegModels;
procedure Example);
var Y,B: Vector;
  X: Matrix;
begin
  X.SetIt(3,2,false,[1.0, 2.0,
                    -3.2, 2.5,
                    8.0, -0.5]);
  Y.SetIt(false, [-3.0, 0.25, 8.0]);
  MulLinFit(B,X,Y,true);
  // B = (18.646428571, -1.9464285714, -9.85 )
end;
