Inversion: MsInversion;
The Inversion property determines the method of initial transformation, that is used for the output variable.
The property is outdated, use InversionInfo.Inversion.
Executing the example requires that the repository contains a modeling container with the MODEL_SPACE identifier. The container includes a model with the MODEL_LINREG identifier. The model uses the method of linear regression (OLS estimation) for calculation.
Sub Main;
Var
MB: IMetabase;
MObj: IMetabaseObject;
Model: IMsModel;
VarTrans: IMsFormulaTransformVariable;
Transf: IMsFormulaTransform;
Tree: IMsFormulaTransformSlicesTree;
Slice: IMsFormulaTransformSlice;
Selector: IMsFormulaTransformSelector;
LinReg: IMsLinearRegressionTransform;
Formula: IMsFormula;
Begin
MB := MetabaseClass.Active;
MObj := MB.ItemByIdNamespace("MODEL_LINREG", MB.ItemById("MODEL_SPACE").Key).Edit;
Model := MObj As IMsModel;
VarTrans := Model.Transform.Outputs.Item(0);
Tree := VarTrans.SlicesTree(VarTrans);
Slice := Tree.CreateSlice(1);
Selector := Model.Transform.CreateSelector;
Selector.Slice := Slice;
Formula := Model.Transform.Transform(Selector);
LinReg := Formula.Method As IMsLinearRegressionTransform;
LinReg.Inversion := MsInversion.DLog;
LinReg.InversionLag := MsInversionLag.PrecidingYear;
MObj.Save;
End Sub Main;
After executing the example the way of transformation of output variable, that is, a difference of logarithms, the transformation period, that is, the appropriate period of the last year, is set for the model.
