IDependenceForm.Fitted

Syntax

Fitted: Array;

Description

The Fitted property returns array of values of dependence form modeling series without seasonality.

Example

Sub Main;

Var

trend: SmCurveEstimation;

d0: Double;

status, i: Integer;

ar: Array Of Double;

Forms: IDependenceForms;

Dep: IDependenceForm;
