infer_mcnemar_test {inferr}

McNemar Test

Description

Test if the proportions of two dichotomous variables are equal in the same population.

Usage

infer_mcnemar_test(data, x = NULL, y = NULL)

Arguments

data

a data.frame or tibble

x

factor; column in data

y

factor; column in data

statistic

chi square statistic

df

degrees of freedom

pvalue

p-value

exactp

exact p-value

cstat

continuity correction chi square statistic

cpvalue

continuity correction p-value

kappa

kappa coefficient; measure of interrater agreement

std_err

asymptotic standard error

kappa_cil

95% kappa lower confidence limit

kappa_ciu

95% kappa upper confidence limit

cases

cases

controls
