f_VIF: Compute Variance Inflation Factors for gene sets

In CBMR-Single-Cell-Omics-Platform/SCOPfunctions: Single Cell Omics Platform Functions

Description

Utility function to compute Variance Inflation Factors for gene sets using an expression dataset in order to account for inter-gene correlation in gene sets derived from expression data

Usage

f_VIF(datExpr, list_genesets)

Arguments

datExpr	gene * cell expression matrix with row and column names
list_genesets	list of genesets, using same gene names as datExpr

Value

list of 2-vectors, one per geneset. First vector element is VIF, second is mean Pearson's rho correlation.
