IMsModelCalculation.ClearSeriesOnWarning

Syntax

ClearSeriesOnWarning: Boolean;

Description

The ClearSeriesOnWarning property determines whether the output series is empty on occurring the warning.

Comments

Available values:

True. The output series will be empty. If nested function is used in the equation, calculation is continued.
False. Default value. Output series data will not be changed.

Example

Executing the example requires that the repository contains a modeling container with the MS identifier which contains a non-linear regression model (OLS estimation) with the MODEL identifier.

Add links to the Metabase, Ms system assemblies.

Sub UserCalc;
Var
    MB: IMetabase;
    Model: IMsModel;
    Transform: IMsFormulaTransform;
    VarTrans: IMsFormulaTransformVariable;
    Tree: IMsFormulaTransformSlicesTree;
    Slice: IMsFormulaTransformSlice;
    Selector: IMsFormulaTransformSelector;
    Formula: IMsFormula;
    LinReg: IMsLinearRegressionTransform;
    Coord: IMsFormulaTransformCoord;
    Calc: IMsModelCalculation;
    CalcRes: IMsModelCalculationResult;
Begin
    MB := MetabaseClass.Active;
    // Get the model
    Model := MB.ItemByIdNamespace("MODEL", MB.ItemById("MS").Key).Edit As IMsModel;
    // Get model calculation parameters
    Transform := Model.Transform;
    VarTrans := Transform.Outputs.Item(0);
    Tree := VarTrans.SlicesTree(VarTrans);
    Slice := Tree.CreateSlice(1);
    Selector := Model.Output.Item(0).Transform.CreateSelector;
    Selector.Slice := Slice;
    Formula := Model.Transform.Transform(Selector);
    // Prepare model calculation
    LinReg := Formula.Method As IMsLinearRegressionTransform;
    Coord := Model.Transform.CreateCoord(VarTrans);
    Calc := Model.CreateCalculation;
    // Set calculation periods
    Calc.Period.IdentificationStartDate := DateTime.Parse("01.01.1990");
    Calc.Period.IdentificationEndDate := DateTime.Parse("31.12.2009");
    Calc.Period.ForecastStartDate := DateTime.Parse("01.01.2010");
    Calc.Period.ForecastEndDate := DateTime.Parse("31.12.2013");
    // Set mode of data output to output series
    Calc.ClearSeriesOnWarning := True;
    // Perform model identification
    LinReg.Identify(Calc As IMsMethodCalculation, Coord);
    // Save changes
    (Model As IMetabaseObject).Save;
End Sub UserCalc;

After executing the example the model is calculated for the specified period. If on calculating the warning occurred, the output series is cleared.
