IStatistics.Percentile

Syntax

Percentile(Data: Array; Percent: Double): Double;

Parameters

Data. Data array that determines relative position;

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

Description

The Percentile method returns the k-th percentile for interval values.

Comments

Use this function to determine an acceptability threshold.

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

Example

Sub Main;

Var

st: Statistics;

d0: Double;

y: Array Of Double;

Begin

y := New Double[7];

y[00] := 6;

y[01] := 7;

y[02] := 9;

y[03] := 15;

y[04] := 21;

y[05] := 24;

y[06] := 25;

st := New Statistics.Create;

d0 := st.Percentile(y,0.3);

Debug.WriteLine("30th percentile: " + d0.ToString);

End Sub Main;

Executing the example displays the 30-th percentile for the specified data array:

Module execution started

30-th percentile: 8.5999999999999996
