Description

Integration of differential expression and differential splice scores with a rank-based strategy, which simultaneously integrates observed scores and permutation scores using the same ranks.

Usage

1
rankCombine(DEscore, DSscore, DEscoreMat, DSscoreMat, DEweight = 0.5)

Arguments

DEscore

differential expression scores, normalized.

DSscore

differential splice scores, normalized.

DEscoreMat

differential expression scores in permuted data sets, normalized.

DSscoreMat

differential splice scores in permuted data sets, normalized.

DEweight

any number between 0 and 1 (included), the weight of differential expression scores (so the weight for differential splice is (1-DEweight)).

Details

This integration method is also known as integration with global ranks. See Wang and Cairns (2013) for details.

Value

A list with two elements geneScore and genePermuteScore.
