IMsGreyForecastTransform.Residuals

Syntax

Description

The Residuals property determines the variable to which residual series is unloaded on modeling problem calculation.

Comments

The property is outdated, use IMsMethodSeries.Residuals.

Example

Executing the example requires a modeling problem in the container. The first model of the problem uses the Grey forecast for calculation.

Sub Main;

Var

MB: IMetabase;

KontKey: Integer;

MObj: IMetabaseObject;

Problem: IMsProblem;

CalcSett: IMsProblemCalculationSettings;

Calculation: IMsProblemCalculation;

Model: IMsModel;

Trans: IMsFormulaTransform;

VarTrans: IMsFormulaTransformVariable;

Tree: IMsFormulaTransformSlicesTree;

Slice: IMsFormulaTransformSlice;

Selector: IMsFormulaTransformSelector;

Formula: IMsFormula;

Grey: IMsGreyForecastTransform;

Residuals_Var: IVariableStub;

Begin

MB := MetabaseClass.Active;

KontKey := MB.ItemById("KONT_MODEL").Key;

MObj := MB.ItemByIdNamespace("PROBLEM_1", KontKey).Edit;

//variables to which the data are loaded

Residuals_Var := MB.ItemByIdNamespace("Residuals_Var", KontKey).Edit As IVariableStub;

Problem := MObj As IMsProblem;

Model := (Problem.MetaModel.CalculationChain.Item(0) As IMsCalculationChainModel).Model;

Model := (Model As IMetabaseObject).Edit As IMsModel;

Model.Transform.Series.Add(Residuals_Var);

Trans := Model.Transform;

VarTrans := Trans.Outputs.Item(0);

Tree := VarTrans.SlicesTree(VarTrans);

Slice := Tree.CreateSlice(1);

Selector := Model.Transform.CreateSelector;

Selector.Slice := Slice;

Formula := Model.Transform.Transform(Selector);

Grey := Formula.Method As IMsGreyForecastTransform;

//residual series

Grey.Residuals := Residuals_Var;

//parameters for problem calculation

CalcSett := Problem.CreateCalculationSettings;

Calculation := Problem.Calculate(CalcSett);

Calculation.Run;

(Model As IMetabaseObject).Save;

MObj.Save;

End Sub Main;

After executing the example, the variable with the Residuals_Var identifier is added to the list of output variables of the model. After calculating the problem, the residual series is unloaded to it.
