empPvals (Package: qvalue) : Calculate p-values from a set of observed test statistics and

Calculates p-values from a set of observed test statistics and simulated null test statistics

hedenfalk (Package: qvalue) : P-values and test-statistics from the Hedenfalk et al. (2001) gene

The data from the breast cancer gene expression study of Hedenfalk et al. (2001) were obtained and analyzed. A comparison was made between 3,226 genes of two mutation types, BRCA1 (7 arrays) and BRCA2 (8 arrays). The data included here are p-values, test-statistics, and permutation null test-statistics obtained from a two-sample t-test analysis on a set of 3170 genes, as described in Storey and Tibshirani (2003).

plot.qvalue (Package: qvalue) : Plotting function for q-value object

Graphical display of the q-value object

qvalue (Package: qvalue) : Estimate the q-values for a given set of p-values

Estimate the q-values for a given set of p-values. The q-value of a test measures the proportion of false positives incurred (called the false discovery rate) when that particular test is called significant.

summary.qvalue (Package: qvalue) : Display q-value object

Display summary information for a q-value object.

write.qvalue (Package: qvalue) : Write results to file

Write the results of the q-value object to a file.
