SortedArrayStatisticsQuantile Method
Estimates the tau-th quantile from the sorted data array (ascending). The tau-th quantile is the data value where the cumulative distribution function crosses tau. Approximately median-unbiased regardless of the sample distribution (R8).

Namespace: MathNet.Numerics.Statistics
Assembly: MathNet.Numerics (in MathNet.Numerics.dll) Version: 3.7
Syntax
C#
Copy
public static double Quantile(
	double[] data,
	double tau
)

Parameters

data
Type: SystemDouble
Sample array, must be sorted ascendingly.
tau
Type: SystemDouble
Quantile selector, between 0.0 and 1.0 (inclusive).

Return Value

Type: Double
Remarks
R-8, SciPy-(1/3,1/3): Linear interpolation of the approximate medians for order statistics. When tau < (2/3) / (N + 1/3), use x1. When tau >= (N - 1/3) / (N + 1/3), use xN.
