STAC 1.2 – Significance Testing for Aberrant Copy-Number

STAC 1.2

:: DESCRIPTION

STAC (Significance Testing for Aberrant Copy-Number) is a method for testing the significance of DNA copy number aberrations across multiple array-CGH experiments. It utilizes two complementary statistics in combination with a novel search strategy. The significance of both statistics is assessed, and P-values are assigned to each location on the genome by using a multiple testing corrected permutation approach. STAC identifies genomic alterations known to be of clinical and biological significance and provides statistical support for 85% of previously reported regions. Moreover, STAC identifies numerous additional regions of significant gain/loss in these data that warrant further investigation. The P-values provided by STAC can be used to prioritize regions for follow-up study in an unbiased fashion.
