IMsCompositeFormulaTerm.MissingData

Syntax

Description

The property is read-only.

The MissingData property returns parameters of missing data treatment method in composite term values.

Comments

MissingData is accounted if the IMsCompositeFormulaTerm.ApplyMissingData = True.

Example

Executing the example requires that the repository contains a modeling container with the OBJ_MS identifier containing a model with the MODEL identifier. The model is calculated by the linear regression (OLS mark). It is also necessary to add links to the Ms, Metabase and Stat system assemblies.

    Sub UserProc;
    Var
        Mb: IMetabase;
        MsDescrKey: Integer;
        Model: IMsModel;
        ModelTrans: IMsFormulaTransform;
        Formula: IMsFormula;
        Linear: IMsLinearRegressionTransform;
        CompositeTerm: IMsCompositeFormulaTerm;
    Begin
        Mb := MetabaseClass.Active;
        MsDescrKey := Mb.ItemById("OBJ_MS").Key;
    // Get model
        Model := MB.ItemByIdNamespace("MODEL", MsDescrKey).Edit As IMsModel;
        ModelTrans := Model.Transform;
    // Set up model calculation parameters
        Formula := ModelTrans.FormulaItem(0);
        Linear := Formula.Method As IMsLinearRegressionTransform;
        CompositeTerm := Linear.Explanatories.Item(0);
        CompositeTerm.ApplyMissingData := True;
        CompositeTerm.MissingData.Method := MissingDataMethod.AnyValue;
    // Save the parameters of calculation of model
        (Model As IMetabaseObject).Save;
    End Sub UserProc;

After executing the example, missing data treatment is set for the first compound term that is used as a linear regression.
