RegModels.MulLinEval Method ([In] double[], [In] TMtx, [In] TVec, bool)

Collapse All

Evaluates b[0] + b[1]*x[0] + b[2]*x[1] + ... for given values in X vector, parameters in B array, and returns the results in XHat vector.

Syntax
C#
Visual Basic
public static void MulLinEval([In] double[] B, [In] TMtx X, [In] TVec YHat, bool Constant);
Remarks

Size and Complex properties of XHat vector are adjusted automatically. 

Note Use this version if you want to evaluate multiple linear function for multiple values at the same time. This is a lot faster than calling single value version for each x value.

Example
using Dew.Math; using Dew.Stats.Units; namespace Dew.Examples { private void Example() { Matrix X = new Matrix(0,0); Vector YHat = new Vector(0); X.SetIt(3,3,false,new double[]{2, -3, 5, 1, 6, -4, 8, 7, 9}); // Evaluate, no constant term! RegModels.MulLinEval(new double[] {1.0, 0.5, -2.0},X,YHat, false); // YHat = (-9.5, 12, -6.5) } }
