infer_binom_calc {inferr}

Binomial Test

Description

Test whether the proportion of successes on a two-level categorical dependent variable significantly differs from a hypothesized value.

Usage

infer_binom_calc(n, success, prob = 0.5, ...)

infer_binom_test(data, variable, prob = 0.5)

Arguments

n

number of observations

success

number of successes

prob

assumed probability of success on a trial

...

additional arguments passed to or from other methods

data

a data.frame or a tibble

variable

factor; column in data

Value

infer_binom_test returns an object of class "infer_binom_test". An object of class "infer_binom_test" is a list containing the following components:

exp_k

expected number of successes

exp_p

expected probability of success

k

number of successes

n

number of observations

obs_p

assumed probability of success

pval_lower

lower one sided p value

pval_upper

upper one sided p value

Deprecated Functions

binom_calc() and binom_test() have been deprecated. Instead use infer_binom_cal() and infer_binom_test().
