IMsFormulaTerm.TermInfo

Syntax

Description

The TermInfo property determines term parameters.

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 a output variable, and also the Var_Factor variable, used as a factor.

After executing the example, a new model is created in the modeling container. An output variable and one input variable are added to the created model. To compose the equation the term that refers to the input variable slice is created. The way of initial transformation of data and lag is changed for the term. The method of non-linear regression is used for model calculation.
