comp_FDR: Compute a decision's false detection rate (FDR) from probabilities.

Description

comp_FDR computes the false detection rate FDR from 3 essential probabilities prev, sens, and spec.

Usage

comp_FDR(prev, sens, spec)

Arguments

prev

The condition's prevalence prev (i.e., the probability of condition being TRUE).

sens

The decision's sensitivity sens (i.e., the conditional probability of a positive decision provided that the condition is TRUE).

spec

The decision's specificity value spec (i.e., the conditional probability of a negative decision provided that the condition is FALSE).

Value

The false detection rate FDR as a probability. A warning is provided for NaN values.

Details

comp_FDR uses probabilities (not frequencies) and does not round results.

comp_FDR(.50, .333, .666)  # => FDR = 0.5007 = (1 - PPV)
