Results in the Nth percentile of the values in the input buffer.

Percentile

Overview

This operator calculates the specified percentile of the input buffer, and will place this value at the output as a scalar.

The algorithm used, uses linear interpolation between the two nearest ranks, to get the result.

Operator ports

Input V_in: Specific sample type, see below.

Output S_out: Floating point values

Details

The Percentile operator works as follows:
Firstly, the (real) values in the buffer at the input are ordered from small to large, to get the order statistics. Then the value is found that is greater or equal to N percent of all values in the buffer. N is the percentile value you specify in the properties.

If the Nth order statistic is not an integer, but equal to r plus some fraction, then a weighted average of the rth and the (r + 1)th order statistic is calculated.

Using this operator, you can also find the median, the quartiles and deciles of the sample.
