TopDown_TMTI | R Documentation |
TopDown TMTI algorithm for estimating a 1-alpha confidence set for the number of false hypotheses among a set.
TopDown_TMTI( pvals, subset = NULL, alpha = 0.05, gammaList = NULL, verbose = TRUE, tau = NULL, K = NULL, is.sorted = FALSE, mc.cores = 1L, chunksize = 4 * mc.cores, direction = "binary", ... )
pvals |
A vector of p-values. |
subset |
Numeric vector specifying a subset a p-values to estimate a confidence set for the number of false hypotheses for. Defaults to NULL corresponding to estimating a confidence set for the number of false hypotheses in the entire set. |
alpha |
Level in [0,1] at which to generate confidence set. Defaults to 0.05. |
gammaList |
List of pre-specified gamma functions. If NULL, the functions will be approximated by bootstrap assuming independence. Defaults to NULL. |
verbose |
Logical, indicating whether or not to write out the progress. Defaults to TRUE. |
tau |
Numerical (in (0,1)); threshold to use in tTMTI. If set to NULL, then either TMTI (default) or rtTMTI is used. |
K |
Integer; Number of smallest p-values to use in rtTMTI. If se to NULL, then either TMTI (default) or tTMTI is used. |
is.sorted |
Logical, indicating whether the supplied p-values are already is.sorted. Defaults to FALSE. |
mc.cores |
Number of cores to parallelize onto. |
chunksize |
Integer indicating the size of chunks to parallelize. E.g., if setting chunksize = mc.cores, each time a parallel computation is set up, each worker will perform only a single task. If mc.cores > chunksize, some threads will be inactive. |
direction |
A string indicating whether to perform a binary search ('binary'/'b') or decreasing ('decreasing'/'d') search. Defaults to 'binary', which has better computational complexity. |
... |
Additional parameters. |
