P-value correction

From Rosetta Code
Task
P-value correction
You are encouraged to solve this task according to the task description, using any language you may know.

Given a list of p-values, adjust the p-values for multiple comparisons. This is done in order to control the false positive, or Type 1 error rate.

This is also known as the "false discovery rate" (FDR). After adjustment, the p-values will be higher but still inside [0,1].

The adjusted p-values are sometimes called "q-values".


Task

Given one list of p-values, return the p-values correcting for multiple comparisons

There are several methods to do this, see:


Each method has its own advantages and disadvantages.

C

Version 1

Works with: C99
Translation of: R

This work is based on R source code covered by the GPL license. It is thus a modified version, also covered by the GPL. See the FAQ about GNU licenses.

This work is a translation of the R source code. In order to confirm that the new function is working correctly, each value is compared to R's output and a cumulative absolute error is returned.

The C function p_adjust is designed to work as similarly to the R function p.adjust as possible, and is able to do any one of the methods.

This program, for example, fdr.c, can be compiled by

gcc -o fdr fdr.c -Wall -pedantic -std=c11 -lm -O4

or

clang -o fdr fdr.c -Wall -pedantic -std=c11 -lm -O4.

Version 2

Translation of: Raku

To avoid licensing issues, this version follows the approach of the Raku entry of which it is a partial translation. However, the correction routines themselves have been coded independently, common code factored out into separate functions (analogous to Raku) and (apart from the Šidák method) agree with the Raku results.

The qqvalue package on SSC provides the equivalent of the R function p.adjust.

First, install the package with:

ssc install qqvalue

Given a dataset containing the p-values in a variable, the qqvalue command generates another variable with the adjusted p-values. Here is an example showing the result with all implemented methods:
