GetStabilityPCA {GeneSelector}R Documentation

Stability measures for gene rankings

Description

A principal components analysis is applied to the matrix storing the different rankings for each gene. The ratio of the first eigenvalue to the sum of all eigenvalues is used as stability measure. If stability is high/variability is low, then the first principal component will explain a large amount of the overall variation, leading to large first eigenvalue.

Usage

Arguments

RR An object of class RepeatRanking
