Title:

Group Testing Procedures for Signal Detection and Goodness-of-Fit

Version:

0.3.0

Author:

Maintainer:

Hong Zhang <hzhang@wpi.edu>

Description:

It provides cumulative distribution function (CDF), quantile, p-value, statistical power calculator and random number generator for a collection of group-testing procedures, including the Higher Criticism tests, the one-sided Kolmogorov-Smirnov tests, the one-sided Berk-Jones tests, the one-sided phi-divergence tests, etc. The input are a group of p-values. The null hypothesis is that they are i.i.d. Uniform(0,1). In the context of signal detection, the null hypothesis means no signals. In the context of the goodness-of-fit testing, which contrasts a group of i.i.d. random variables to a given continuous distribution, the input p-values can be obtained by the CDF transformation. The null hypothesis means that these random variables follow the given distribution. For reference, see [1]Hong Zhang, Jiashun Jin and Zheyang Wu.

- vector of search range ends (at the k1th smallest p-value).

S

- vector of the phi-divergence test parameters.

onesided

- TRUE if the input p-values are one-sided.

method

ei

- the eigenvalues of M if available.

Value
