poolr-package: Methods for Pooling P-Values from (Dependent) Tests

In poolr: Methods for Pooling P-Values from (Dependent) Tests

Description

\loadmathjax

The poolr package contains functions for pooling/combining the results (i.e., \mjseqnp-values) from (dependent) hypothesis tests. Included are Fisher's method, Stouffer's method, the inverse chi-square method, the Bonferroni method, Tippett's method, and the binomial test. Each method can be adjusted based on an estimate of the effective number of tests or using empirically-derived null distribution using pseudo replicates. For Fisher's, Stouffer's, and the inverse chi-square method, direct generalizations based on multivariate theory are also available (leading to Brown's method, Strube's method, and the generalized inverse chi-square method). For more details, see:

• fisher: for Fisher's method (and Brown's method)

• stouffer: for Stouffer's method (and Strube's method)

• invchisq: for the inverse chi-square method

• bonferroni: for the Bonferroni method

• tippett: for Tippett's method

• binomtest: for the binomial test

Note that you can also read the documentation of the package online at https://ozancinar.github.io/poolr/ (where it is nicely formatted and the output from all examples is provided).
