IStatistics.AveDev

Syntax

AveDev(Value: Array): Double;

Parameters

Value. A set of values, for which you find the average of absolute deviations.

Description

The AveDev method returns the average of absolute values of data point deviations from the average.

Comments

This value is a measure of data set spread.

Example

To execute the example, add a link to the Stat system assembly.

Sub UserProc;
Var
    st: Statistics;
    d0: Double;
    y: Array Of Double;
Begin
    y := New Double[10];
    y[00] := 1.6;
    y[01] := 1.7;
    y[02] := 1.8;
    y[03] := 1.9;
    y[04] := 2;
    y[05] := 2.1;
    y[06] := 2.2;
    y[07] := 2.3;
    y[08] := 2.4;
    y[09] := 2.8;
    st := New Statistics.Create;
    d0 := st.AveDev(y);
    Debug.WriteLine("Average of absolute deviation values: " + d0.ToString);
End Sub UserProc;

After you have executed this example the console window shows the measure of data set spread:

Unit execution started
