IEmLinearRegressionSettings.Explained

Fore syntax

Explained: IEmSerie;

Fore.NET syntax

Explained: Prognoz.Platform.Interop.Modeller.IEmSerie;

Description

The Explained property determines an explained series.

Comments

If an explained series is no specified, correct calculation of the Linear Regression method is not possible.

Fore example

To execute the example, add a link to the Modeller system assembly.

Sub LinearRegression;
Var
    ExprMod: IExpressModeller;
    Ar: Array[14] Of Double;
    Serie: IEmSerie;
    Sett: IEmLinearRegressionSettings;
    SList: IEmSeriesList;
    Period: IEmPeriodSettings;
Begin
    ExprMod := New ExpressModeller.Create;
    Sett := ExprMod.CreateLinearRegressionSettings;
    // Setting explained series
    Ar[0] := 56; Ar[1] := 45; Ar[2] := 23; Ar[3] := 45;
    Ar[4] := 65; Ar[5] := 23; Ar[6] := 54; Ar[7] := 87;
    Ar[8] := 67; Ar[9] := 98; Ar[10] := 89; Ar[13] := 79;
    Ar[11] := Double.Nan; Ar[12] := Double.Nan;
    Serie := ExprMod.Series.Add(Ar, "X1", "Data series 1");
    Sett.Explained := Serie;
    // Setting explanatory series
    Ar[0] := 58; Ar[1] := 50; Ar[2] := 26; Ar[4] := 72;
    Ar[5] := 28; Ar[6] := 62; Ar[7] := 95; Ar[8] := 74;
    Ar[10] := 94; Ar[11] := 100; Ar[12] := 54; Ar[13] := 81;
    Ar[3] := Double.Nan; Ar[9] := Double.Nan;
    Serie := ExprMod.Series.Add(Ar, "X2", "Data series 2");
    SList := Sett.Explanatories;
    SList.Add(Serie);
    // Removing constant from the calculations
    Sett.HasConstant := False;
    // Setting calculation periods
    Period := Sett.Period;
    Period.BeginPeriod := 0;
    Period.EndPeriod := 13;
    Period.EndFore := 4;
    // Performing calculation
    ExprMod.EvaluateMethod("C:\LinearRegression.html", Sett, True);
End Sub LinearRegression;

Example execution result: the Linear Regression method is calculated with set parameters, calculation report is saved to the file C:\LinearRegression.html.
