IStatistics.PercentileDcml

Syntax

PercentileDcml(Data: 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.

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.
