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 estimation). 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 model calculation parameters
        (Model As IMetabaseObject).Save;
    End Sub UserProc;

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