test_veris_ratio: Test the ratio of Ea to Eb

In vz-risk/verisr: Tools for working with VERIS objects

Test the ratio of Ea to Eb

Description

Often we want to create quotes of the form "X is N times more/less likely than y in Z" This function provides a test for such quotes. It checks that the ratio is within the ci.level credible interval and that the credible interval does not include 1 (indicating that we lack the ci.level confidence in the direciton of the ratio)

Usage

test_veris_ratio(
  chunk,
  Ea,
  Eb,
  ratio,
  direction,
  ci.level = 0.05,
  reps = 1000,
  quietly = FALSE,
  visualize = FALSE
)

Arguments

chunk	getenumCI() output
Ea	Enumeration A. e.g. "action.Error"
Eb	Enumeration B. e.g. "action.Misuse"
ratio	The ratio of Ea to Eb to test as a number. Must be greater than 1.
direction	the direction to test ("greater" or "less")
ci.level	the confidence level to test against
reps	number of simulations to conduct
quietly	do not produce textual output
visualize	produce visual output

Value

a logical TRUE/FALSE to the hypothesis
