View source: R/dI.R

Description

Calculates (1-alpha) lower confidence bounds for the set-wise of false null hypotheses.

Usage

1
dI(ix, cv, pvalues, iterative, approx, ncomb, ...)

Arguments

ix

numeric vector. It refers to the set-wise hypotheses considered.

cv

numeric vector. It refers to the critical vector computed by criticalVector.

pvalues

matrix of pvalues with dimensions m \times B.

iterative

Boolean value. If iterative = TRUE, the iterative method for improvement of confidence envelopes is applied. Default @FALSE.

approx

Boolean value. Default @TRUE. If you are treating high dimensional data, we suggest to put approx = TRUE to speed up the computation time. Default @TRUE

ncomb

Numeric value. If approx = TRUE, you must decide how many random subcollections (level of approximation) considered. Default 100.

...

further arguments for the iterative approach, i.e., iterative = TRUE.

Value

numeric value: the lower confidence bound for the number of true discoveries concerning the cluster ix specified.
