comp_complete_prob_set: Compute a complete set of probabilities from valid probability inputs.

Description

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.

Value

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

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.

# ways to work:

comp_complete_prob_set(1, NA, .8, NA, .4) # => 1.0 0.2 0.8 0.6 0.4

# watch out for:

comp_complete_prob_set(8, 7, 6, 5, 4)      # => 8 7 6 5 4 + no warning (valid set assumed)
comp_complete_prob_set(8, .8, NA, .7, NA)  # => 8.0 0.8 0.2 0.7 0.3 + no warning (sic)
comp_complete_prob_set(8, 2, NA, 3, NA)    # => 8 2 NA 3 NA + no warning (sic)
