Least Squares subroutine c#

Goal: to create a class with methods to be able to pass in x,y pairs and get back a curve fitted using the proper forumla (suggested: ax2 + by + c). Pass back the a, b, c values. Part 2: Be able to pass to another function the abc values, and new x coordinate and get back the y value. See example. ...for developer to do... is the part I need done. C# class InputPairs { public double x; public double y; public InputPairs(double dx, double dy) { x = dx; y = dy; } } class clsLeastSquaresVarsCurve { ...for developer to do... } ArrayList inputs = new ArrayList(); InputPairs p1 = new InputPairs(1.0, .40); [login to view URL](p1); InputPairs p2 = new InputPairs(2.0, .45); [login to view URL](p2); InputPairs p3 = new InputPairs(3.0, .48); [login to view URL](p3); InputPairs p4 = new InputPairs(4.0, .42); [login to view URL](p4); InputPairs p5 = new InputPairs(5.0, .50); [login to view URL](p5); clsLeastSquaresVars vars = GetLeastSquaresVarsCurve(inputs); double newX = 6.0; double newY = GetNewValue(vars, newX); public clsLeastSquaresVars GetLeastSquaresVarsCurve(ArrayList input) { // find correct quadratic equation // return variables // ... for developer to do ... } public double GetNewValue(clsLeastSquaresVars vars, double XValue) { // using quadratic variables // using XValue // return calculated Y value // ... for developer to do ... ## Deliverables 1) Complete and fully-functional working sample Visual Studio 2003 project with complete source code of all work done. 2) All deliverables will be considered "work made for hire" under U.S. Copyright law.
