In SetTest: Group Testing Procedures for Signal Detection and Goodness-of-Fit

Multiple comparison test using Higher Criticism (HC) statitics.

Description

Multiple comparison test using Higher Criticism (HC) statitics.

Usage

test.hc(prob, M, k0, k1, onesided = FALSE, method = "ecc", ei = NULL)

Arguments

prob	- vector of input p-values.
M	- correlation matrix of input statistics (of the input p-values).
k0	- search range starts from the k0th smallest p-value.
k1	- search range ends at the k1th smallest p-value.
onesided	- TRUE if the input p-values are one-sided.
method	- default = "ecc": the effective correlation coefficient method in reference 2. "ave": the average method in reference 3, which is an earlier version of reference 2. The "ecc" method is more accurate and numerically stable than "ave" method.
ei	- the eigenvalues of M if available.

Value

pvalue - The p-value of the HC test.

hcstat - HC statistic.

location - the order of the input p-values to obtain HC statistic.

Examples

pval.test = runif(10)
test.hc(pval.test, M=diag(10), k0=1, k1=10)
#When the input are statistics#
stat.test = rnorm(20)
p.test = 2*(1 - pnorm(abs(stat.test)))
test.hc(p.test, M=diag(20), k0=1, k1=10)
