IEmClusterAnalysisSettings.ClusterObjects

Fore syntax

ClusterObjects: IEmSeriesList;

Fore.NET syntax

ClusterObjects: Prognoz.Platform.Interop.Modeller.IEmSeriesList;

Description

The ClusterObjects property returns hierarchic cluster analysis objects collection.

Comments

If the objects are not specified, correct calculation of the method is not possible.

Fore example

To execute the example, add links to the Modeller, Stat system assemblies.

Sub ClusterAnalysis;
Var
    ExprMod: IExpressModeller;
    Ar: Array[6] Of Double;
    Series: IEmSeriesList;
    Serie: IEmSerie;
    Sett: IEmClusterAnalysisSettings;
Begin
    ExprMod := New ExpressModeller.Create;
    Sett := ExprMod.CreateClusterAnalysisSettings;
    // Setting cluster analysis objects
    Series := Sett.ClusterObjects;
    Ar[0] := 10; Ar[1] := 20; Ar[2] := 30;
    Ar[3] := 40; Ar[4] := 50; Ar[5] := 60;
    Serie := ExprMod.Series.Add(Ar, "X1", "Data series 1");
    Series.Add(Serie);
    ar[0] := 12; ar[1] := 23; ar[2] := 34;
    ar[3] := 45; ar[4] := 56; ar[5] := 67;
    Serie := ExprMod.Series.Add(Ar, "X2", "Data series 2");
    Series.Add(Serie);
    ar[0] := 1; ar[1] := 2; ar[2] := 3;
    ar[3] := 4; ar[4] := 5; ar[5] := 6;
    Serie := ExprMod.Series.Add(Ar, "X3", "Data series 3");
    Series.Add(Serie);
    // Setting link method
    Sett.ClusterLink := ClusterLinkType.CompleteLink;
    // Setting metrics
    Sett.ObjectDistance := ObjectDistanceType.EuclideanSqr;
    // Setting indicators standardization mode
    Sett.Standartization := StandartizationType.ScaleUser;
    // Setting standardization coefficients
    Sett.StdValues := Series.ItemByName("X2");
    // Setting dendogram orientation
    Sett.DendogramOrientation := DendogramOrientationType.North;
    // Setting clusters number
    Sett.ClusterCount := 2;
    // Performing calculation
    ExprMod.EvaluateMethod("C:\ClusterAnalysis.html", Sett, True);
End Sub ClusterAnalysis;

Example execution result: the Hierarchical Cluster Analysis method is calculated with set parameters, calculation report is saved to the file C:\ClusterAnalysis.html.
