FDR

False Discorvery Rate (FDR)

Compute the False Discovery Rate for a vector of p-values and alpha value.

Usage
FDR(pvalues = NULL, alpha = 0.95, dep = 1)

pvalue.FDR(pvalues = NULL, dep = 1)

Arguments
pvalues

Vector of p-values

alpha

Alpha value (level of significance).

dep

Parameter dependence test. By default dep = 1, direct dependence between tests.

Details

FDR method is used for multiple hypothesis testing to correct problems of multiple contrasts. If dep = 1, the tests are positively correlated, for example when many tests are the same contrast. If dep < 1 the tests are negatively correlated.

Value

Return:

  • out.FDR =TRUE. If there are significative differences.

  • pv.FDR p-value for False Discovery Rate test.
