pt.sad

dt.sad

x, q

numeric vector of noncentrality parameter

logical; whether <code>log</code> should be taken.

a small numeric scalar; if the difference between <code>q</code> and <code>ncp</code> is closer than this, results will be computed differently.

epsilon

the way to normalize the approximate density so that it is closer to a true density.

Density and cumulative distribution function of noncentral t-distribution

dt.sad and pt.sad

This package implements method(s) to (approximately
        unbiasedly) estimate the proportion of true null hypotheses,
        i.e., the pi0, when a very large number of hypotheses are
        simultaneously tested, especially for the purpose of (local)
        false discovery rate control for microarray data. It also
        contains functions to estimate the distribution of
        noncentrality parameters from a large number of parametric
        tests.
