IStatistics.GeoMean

Syntax

GeoMean(Values: Array): Double;

Values. Array of data, mean of which you calculate. Array values must be greater than zero.

The GeoMean method returns the geometrical mean of positive number array values.

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.GeoMean(y);

Debug.WriteLine("Geometric mean: " + d0.ToString);

End Sub UserProc;

After executing the example the mean value is output to the console window:
