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

Quantile of phi-divergence statistic under the null hypothesis.

Description

Quantile of phi-divergence statistic under the null hypothesis.

Usage

qphi(
  p,
  M,
  k0,
  k1,
  s = 2,
  t = 30,
  onesided = FALSE,
  method = "ecc",
  ei = NULL,
  err_thr = 1e-04
)

Arguments

p	- a scalar left probability that defines the quantile.
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.
s	- the phi-divergence test parameter.
t	- numerical truncation parameter.
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.
err_thr	- the error threshold. The default value is 1e-4.

Value

Quantile of the phi-divergence statistics.
