IMsFormulaTransformCoord.Dimension

Syntax

Dimension(Index: Integer): IDimInstance;

Parameters

Index. Index of additional dimension.

Description

The Dimension property returns the data of additional dimension, the index of which is passed by the parameter Index.

Example

Executing the example requires that the modeling container includes the model, that uses the method of linear regression for calculation. The output variable contains one additional dimension.

Sub Main;

Var

MB: IMetabase;

Model: IMsModel;

Transform: IMsFormulaTransform;

VarTrans: IMsFormulaTransformVariable;

Tree: IMsFormulaTransformSlicesTree;

Slice: IMsFormulaTransformSlice;

Selector: IMsFormulaTransformSelector;

Formula: IMsFormula;

LinReg: IMsLinearRegressionTransform;

Coord: IMsFormulaTransformCoord;

Calc: IMsModelCalculation;

i: Integer;

Begin

MB := MetabaseClass.Active;

Model := MB.ItemByIdNamespace("Model_1", MB.ItemById("KONT_MODEL").Key).Bind As IMsModel;

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);

LinReg := Formula.Method As IMsLinearRegressionTransform;

Coord := Model.Transform.CreateCoord(VarTrans);

Calc := Model.CreateCalculation;

Calc.Period.IdentificationStartDate := DateTime.ComposeDay(1990, 01, 01);

Calc.Period.IdentificationEndDate := DateTime.ComposeDay(2007, 12, 31);

Calc.Period.ForecastStartDate := DateTime.ComposeDay(2008, 01, 01);

Calc.Period.ForecastEndDate := DateTime.ComposeDay(2010, 12, 31);

i := Coord.Dimension(0).Attributes.Item(0).LookupValue(Bryansk Region);

If i <> -1 Then

Coord.Item(0) := i;

LinReg.Identify(Calc As IMsMethodCalculation, Coord);

Debug.WriteLine(LinReg.Summary(Coord).R2.ToString);

End If;

End Sub Main;

After executing the example, the search is performed by the first attribute of the Bryansk Region value in data of the first additional dimension of the variable; in case the search is successful, factors of the model equation are identified by the given element.
