Quick Start

With Dew Stats for .NET it's not difficult to do complex tasks. Doing multiple linear regression is a peace of cake:

Add Dew.Math.Units, Dew.Math.Editors to the using section.
Drop tMtxMulLinReg component and the Button on the form.
Bring up the TMtxMulLinReg design time editor by double clicking on MtxMulLinReg1.
Define if constant term or weights will be used (this can also be done at runtime via code). Close TMtxMulLinReg editor.
Double click on Button1 and add the following code:

tMtxMulLinReg1.Y.LoadFromFile("c:\temp\yvals.vec"); tMtxMulLinReg1.A.LoadFromFile("c:\temp\system.mtx"); tMtxMulLinReg1.Recalculate(); MtxVecEdit.ViewValues(tMtxMulLinReg1.RegressResult.B,"Regression coefficients",true,false,false);

Other things to try:

Access RegressResult properties (YCalc, Residuals). Draw these values by using Dew.Math.DrawValues method
Load Y,A data from ASCII file (demonstrated in demo). Repeat procedure.
