estErrorRates:

Description

Estimate error rates: false discovery rate (FDR), false non-discovery rate (FNDR), false positve rate (FPR), and false negative rate (FNR) for data with known cluster membership for gene probes.

Usage

estErrorRates(memGenes2.est, memGenes2.true)

Arguments

memGenes2.est

estimated cluster membership for gene probes. memGenes2.est must take only two values 1 and 0.

memGenes2.true

true cluster membership for gene probes. memGenes2.true must take only two values 1 and 0.

Value

A vector of 4 elements: FDR, FNDR, FPR, and FNR.

Details

FDR is the proportion of detected differentially expressed (DE) gene probes that are truly non-differentially expressed (NE) gene probes among all detected DE gene probes. FNDR is the proportion of detected NE gene probes that are truly DE gene probes among all detected NE gene probes. FPR is the proportion of detected DE gene probes that are truly NE gene probes among all truly NE gene probes. FNR is the proportion of detected NE gene probes that are truly DE gene probes among all truly DE gene probes.

Examples

  memGenes2.est = c(1, 1, 1, 0, 0, 0)
  memGenes2.true = c(1, 0, 1, 0, 0, 0)

  err = estErrorRates(memGenes2.est = memGenes2.est, 
    memGenes2.true = memGenes2.true)
