ISmExponentialSmoothing.Fitted

Syntax

Fitted: Array;

Description

The Fitted property returns an array of modeling series values.

Example

Sub Main;

Var

Method: SmExponentialSmoothing;

serie: Array Of Double;

status: Integer;

Seasonal: ISeasonal;

Sub Print(Data: Array Of Double);

Var

i: Integer;

CI: ICultureInfo;

Begin

CI := CultureInfo.Current;

Debug.WriteLine("---Begin---");

For i := 0 To Data.Length - 1 Do

If Double.IsNan(Data[i]) Then

Debug.WriteLine("---empty---");

Else

Debug.WriteLine(CI.FormatDoublePrec(Data[i], 4));

End If;

End For;

Debug.WriteLine("---End---");

End Sub Print;
