IStatistics.DispersionDcml

Fore Syntax

DispersionDcml(Values: Array): Decimal;

Fore.NET Syntax

DispersionDcml(Values: System.Array): decimal;

Parameters

Values. An array of decimal high-precision numbers corresponding to the sampling from universal set.

Description

The DispersionDcml method estimates variance by sample of the Decimal type.

Comments

To define numbers of the Decimal type in the array, it is necessary to write the "m" character after the value of each number. For example: 0.001m.

To get standard deviation by the sampling of numbers of the Decimal type, use the IStatistics.StDevDcml method.

Fore Example

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

Sub UserProc;
Var
    st: Statistics;
    a: Array[3] Of Variant;
    s: Decimal;
Begin
    st := New Statistics.Create;
    a[0] := 0.858739815m;
    a[1] := 0.148393423m;
    a[2] := 0.537711777m;
    s:=st.DispersionDcml(a);
    Debug.WriteLine("Variance: " + s.ToString);
End Sub UserProc;

After executing the example the console window displays the value of variance of decimal high-precision numbers.

Fore.NET Example

The requirements and result of the Fore.NET example execution match with those in the Fore example.

Imports Prognoz.Platform.Interop.Stat;
…
Public Shared Sub Main(Params: StartParams);
Var
    st: Statistics;
    a: Array[3] Of object;
    s: decimal;
Begin
    st := New Statistics.Create();
    a[0] := 0.858739815m;
    a[1] := 0.148393423m;
    a[2] := 0.537711777m;
    s:=st.DispersionDcml(a);
    System.Diagnostics.Debug.WriteLine("Variance: " + s.ToString());
End Sub;
