IMsCurveEstimationTransform.DependenceFormIncluded

Syntax

DependenceFormIncluded(Index: Integer): Boolean;

Parameters

Index. Index of the model. To select the required model it is recommended to use the DependenceType enumerable type.

Description

The DependenceFormIncluded property determines, which dependency types should be calculated and further estimated using the model selection criterion.

Example

Executing the example requires that the repository contains a modeling container with the KONT_MODEL identifier. The container contains the Var_1 variable, further used as an output one.

End Sub Main;

After executing the example a model is created in the modeling container. The universal trend method is used for the model calculation. As a result of the method execution the compound, logarithmic and hyperbolic dependencies are calculated. The resulting model is selected by the least value of sum of squared residuals.
