Computes the False Discovery Proportion (upper-bound) as a ratio of the PFER
(upper-bound) over the number of stably selected features. In stability
selection, the FDP corresponds to the expected proportion of stably selected
features that are not relevant to the outcome (i.e. proportion of False
Positives among stably selected features).
Usage
FDP(selprop, PFER, pi)
Value
The estimated upper-bound in FDP.
Arguments
selprop
matrix or vector of selection proportions.
PFER
Per Family Error Rate.
pi
threshold in selection proportions.
