IDependenceForm.ResidualsSeason

Syntax

ResidualsSeason: Array;

Description

The ResidualsSeason property returns a dependency form residual series with seasonality.

Example

Sub Main;

Var

trend: SmCurveEstimation;

d0: Double;

status, i: Integer;

ar: Array Of Double;

Forms: IDependenceForms;

Dep: IDependenceForm;

If status <> 0 Then

Debug.WriteLine(trend.Errors);

Else

Forms := trend.DependenceForms;

Dep := Forms.Item(1);

Debug.WriteLine("Dependence form " + Dep.DisplayName);

Debug.WriteLine("=== Residual series with seasonality ===");

For i := 0 To Dep.ResidualsSeason.Length -1 Do

d0 := Dep.ResidualsSeason[i];

Debug.WriteLine(i.ToString + ": " + d0.ToString);

End For;

End If;

End Sub Main;
