IMissingData.SpecifiedVector

Syntax

SpecifiedVector: Array;

Description

The SpecifiedVector property defines additional parameters for the missing data treatment methods Pattern (MissingDataMethod.Pattern) and Overlay (MissingDataMethod.Overlay).

Comments

For these methods the SpecifiedVector property determines the series, based on which the missing data of modeled series are to be substituted.

For other methods of missing data treatment this property is not relevant.

Example

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

Sub UserProc;
Var
    FillGaps: SmFillGapsProcedure;
    Series: ISlSeries;
    serie, OverlaySerie: Array[10] Of Double;
    MD: IMissingData;
    // Data output procedure
    Sub Print(Data: Array Of Double);
    Var
        i: Integer;
    Begin
        Debug.Indent;
        For i := 0 To Data.Length - 1 Do
            If Double.IsNan(Data[i]) Then
                Debug.WriteLine("----empty---");
                Else
                    Debug.WriteLine(i.ToString + " " + Data[i].ToString);
            End If;
        End For;
        Debug.Unindent;

    End Sub Print;
Begin
    FillGaps := New SmFillGapsProcedure.Create;
    // Modeled series
    serie[0] := 0;
    serie[1] := 0;
    serie[2] := 0.878471616;
    serie[3] := 0.85401205;
    serie[4] := Double.Nan;
    serie[5] := 1.28083579;
    serie[6] := Double.Nan;
    serie[7] := 4.237308214;
    serie[8] := 4.864879297;
    serie[9] := 7.765499027;
    Series := FillGaps.InputSeries;
    Series.Add.Value := serie;
    // The series from which values are taken to fill missing data
    OverlaySerie[0] := 0;
    OverlaySerie[1] := 1;

    OverlaySerie[2] := 2;
    OverlaySerie[3] := 3;
    OverlaySerie[4] := 4;
    OverlaySerie[5] := 5;
    OverlaySerie[6] := 6;
    OverlaySerie[7] := 7;
    OverlaySerie[8] := 8;
    OverlaySerie[9] := 9;
    Series := FillGaps.InputSeries;
    Series.Add.Value := serie;
    MD := FillGaps.MissingData;
    // Method of missing data treatment
    MD.Method := MissingDataMethod.Overlay;
    // Advanced parameter for methods of missing data treatment "Values of specified series"
    MD.SpecifiedVector := OverlaySerie;
    Debug.WriteLine("Source series");
    Print(Series.Item(0).Value);
    FillGaps.Execute;
    Debug.WriteLine("Output series");
    Print(Series.Item(0).Value);
End Sub UserProc;

After executing the example the console window displays source series and the series calculated using the method of missing data treatment Values of specified series.
