One Sample Test of Proportion

Description

ifr_os_prop_test compares proportion in one group to a specified population proportion.

Usage

ifr_os_prop_test(
  data,
  variable = NULL,
  prob = 0.5,
  phat = 0.5,
  alternative = c("both", "less", "greater", "all")
)

## Default S3 method:
ifr_os_prop_test(
  data,
  variable = NULL,
  prob = 0.5,
  phat = 0.5,
  alternative = c("both", "less", "greater", "all")
)

Arguments

data	numeric vector of length 1 or a data.frame or tibble
variable	factor; column in data
prob	hypothesised proportion
phat	observed proportion
alternative	a character string specifying the alternative hypothesis, must be one of "both" (default), "greater", "less" or "all". You can specify just the initial letter.

Value

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

n	number of observations
phat	proportion of 1's
p	assumed probability of success
z	z statistic
sig	p-value for z statistic
alt	alternative hypothesis
obs	observed number of 0's and 1's
exp	expected number of 0's and 1's
deviation	deviation of observed from expected
std	standardized resiudals
