Package: twilight
Description: In a typical microarray setting with gene expression data
observed under two conditions, the local false discovery rate
describes the probability that a gene is not differentially
expressed between the two conditions given its corrresponding
observed score or p-value level. The resulting curve of
p-values versus local false discovery rate offers an insight
into the twilight zone between clear differential and clear
non-differential gene expression. Package TWILIGHT contains
two main functions: Function twilight.pval performs a
two-condition test on differences in means for a given input
matrix or expression set and computes permutation based
p-values. Function twilight performs a stochastic downhill
search to estimate local false discovery rates and effect size
distributions.
