In such conditions, standard tests tend to be overly conservative, and\nfail thus to detect significant effects in the data.\n\nThe m-test is a classical statistical test in the sense of defining significance\nwith the conventional bound on Type I errors. On the other hand, it is based\non Bayesian model selection, and thus takes into account uncertainty about the\nmodel's parameters, mitigating the problem of small samples size.\n\nThe m-test has been found to generally have a higher power (smaller fraction of\nType II errors) than a t-test error for small sample sizes (3 to 100 samples).\n\n[1] Berkes, P., Fiser, J.

The library is\ndistributed with tables for p-values (type I error) for N=3,4,...,20\nand for N=30,40,...,100. These tables cover the most common cases. New\ntables are computed when needed, although completion might take a few\nhours. Type II error tables are not included to keep the package size\nsmall.\n\nSee `scripts\\compute_basic_tables.py` for an example script to\npre-compute tables you might need. The script makes use of the `joblib\n`_ library to distribute the\ncomputations on multiple cores.\n\nDependencies\n============\n\n`mtest` requires `SciPy `_ and `PyMC `_.\n\nLicense\n=======\n\n`mtest` is released under the GPL v3.
