qch-package | R Documentation |
Provides functions for the joint analysis of Q sets of p-values obtained for the same list of items. This joint analysis is performed by querying a composite hypothesis, i.e. an arbitrary complex combination of simple hypotheses, as described in Mary-Huard et al. (2021) \Sexpr[results=rd]{tools:::Rd_expr_doi("10.1093/bioinformatics/btab592")} and De Walsche et al.(2023) \Sexpr[results=rd]{tools:::Rd_expr_doi("10.1101/2024.03.17.585412")}. In this approach, the Q-uplet of p-values associated with each item is distributed as a multivariate mixture, where each of the 2^Q components corresponds to a specific combination of simple hypotheses. The dependence between the p-value series is considered using a Gaussian copula function. A p-value for the composite hypothesis test is derived from the posterior probabilities.
The main functions of the package GetHconfig
, GetH1AtLeast
,
GetH1Equal
,
qch.fit
and qch.test
correspond to the
4 steps for querying a composite hypothesis:
Building all possible combination of simple hypotheses H_0
/H_1
Composite alternative hypothesis formulation
Inferring the null distribution
Testing the composite null hypothesis
