IStatPeriod.LastPoint

Syntax

LastPoint: Integer;

Description

The LastPoint property determines the end point of the sample period.

Comments

The range of values for the last points of the sample period starts from one.

By default, the property value is -1, in this case the value of the last point of the sample period is defined automatically.

Example

Sub Main;

Var

Exp: SmExponentialSmoothing;

Fact: Array Of Double;

Period: IStatPeriod;

r: Double;

i: Integer;

Begin

Exp := New SmExponentialSmoothing.Create;

Fact := New Double[9];

Debug.WriteLine("== Source series ==");

For i := 0 To 8 Do

Fact[i] := 1230 + i*302;

Debug.WriteLine(Fact[i]);

End For;

Exp.Serie.Value := Fact;

Period := Exp.ModelPeriod;

Period.FirstPoint := 0; // starting point of the sample period

Period.LastPoint := 5; // the end point of the sample period

Exp.Execute;

Debug.WriteLine("== Resulting series ==");

For i := 0 To Exp.Forecast.LastPoint - 1 Do

r := Exp.Fitted[i];

Debug.WriteLine(r.ToString);

End For;

End Sub Main;

After executing the example the console window displays the following result:
