calc_obs_agree: Calculate observed agreement and confidence interval

In emilelatour/lamisc: Latour's Little Helpers

Calculate observed agreement and confidence interval

Description

This is really just a wrapper for the irr::agree() function from that package, but I wanted to calculate the confidence interval also.

Usage

calc_obs_agree(data, ..., alpha = 0.05, tolerance = 0)

Arguments

data	A data frame or tibble, n subjects (rows) and m raters (columns)
...	Variables or columns of ratings
alpha	Numeric; two-sided type one error, default = 0.05
tolerance	Used in the irr::agree() function; number of successive rating categories that should be regarded as rater agreement (see details).

Details

Missing data are omitted in a listwise way. Using extended percentage agreement (tolerance!=0) is only possible for numerical values. If tolerance equals 1, for example, raters differing by one scale degree are interpreted as agreeing.

Value

A tibble with the following columns

N	Number of subjects
po	Percent agreement among raters
se_po	Standard error of the proportion
conf_low	Lower asymptotic confidence interval
conf_high	Upper asymptotic confidence interval

Examples

library(irr)
data("video")
calc_obs_agree(data = video, rater1:rater4)
calc_obs_agree(data = video, rater1:rater2)
