IStatistics.PercentileDcml

Fore Syntax

PercentileDcml(Data: Array; Percent: Double): Decimal;

Fore.NET Syntax

PercentileDcml(Data: System.Array; Percent: double): decimal;

Parameters

Data. An array of decimal high-precision numbers, which determines relative position.

Percent. Percentile value. Valid values lie in the range: [0; 1].

Description

The PercentileDcml method returns the k-th percentile for values of the Decimal type from the set interval.

Comments

Percentile is used to determine sustainability threshold. If k is not divisible by 1/(n - 1), the Percentile function performs interpolation to calculate the k-th percentile value.

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.

Fore Example

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

Sub UserProc;
Var
    st: Statistics;
    a: Array[5] Of Variant;
    s: Decimal;
Begin
    st := New Statistics.Create;
    a[0] := 0.85m;
    a[1] := 0.14m;
    a[2] := 0.53m;
    a[3] := 0.28m;
    a[4] := 0.31m;
    s:=st.PercentileDcml(a, 0.3);
    Debug.WriteLine("30-th percentile: " + s.ToString);
End Sub UserProc;

After executing the example the console window displays the 30-th percentile for the specified data array.

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[5] Of object;
    s: decimal;
Begin
    st := New Statistics.Create();
    a[0] := 0.85m;
    a[1] := 0.14m;
    a[2] := 0.53m;
    a[3] := 0.28m;
    a[4] := 0.31m;
    s:=st.PercentileDcml(a, 0.3);
    System.Diagnostics.Debug.WriteLine("30-th percentile: " + s.ToString());
End Sub;
