comp_complete_prob_set

Percentile

Compute a complete set of probabilities from valid probability inputs.

comp_complete_prob_set is a function takes a valid set of (3 to 5) probabilities as inputs (as a vector) and returns the complete set of (3 essential and 2 optional) probabilities.

Usage
comp_complete_prob_set(prev, sens = NA, mirt = NA, spec = NA,
  fart = NA)
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). sens is optional when its complement mirt is provided.

mirt

The decision's miss rate mirt (i.e., the conditional probability of a negative decision provided that the condition is TRUE). mirt is optional when its complement sens is provided.

spec

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

fart

The decision's false alarm rate fart (i.e., the conditional probability of a positive decision provided that the condition is FALSE). fart is optional when its complement spec is provided.

Details

Assuming that is_valid_prob_set = TRUE this function uses comp_comp_pair on the two optional pairs (i.e., sens and mirt, and spec and fart) and returns the complete set of 5 probabilities.

Value

A vector of 5 probabilities: c(prev, sens, mirt, spec, fart).
