bhapkar: Bhapkar coefficient of concordance between raters
Description
Calculates the Bhapkar coefficient of concordance for two raters.
Usage
bhapkar(ratings)
Arguments
ratings
n*2 matrix or dataframe, n subjects 2 raters.
Value
A list with class "irrlist" containing the following components:
$methoda character string describing the method.
$subjectsthe number of data objects.
$ratersthe number of raters.
$irr.namethe name of the coefficient (Chisq).
$valuethe value of the coefficient.
$stat.namethe name and df of the test statistic.
$statisticthe value of the test statistic.
$p.valuethe probability of the test statistic.
Details
Missing data are omitted in a listwise way.
The Bhapkar (1966) test is a more powerful alternative to the Stuart-Maxwell test.
Both tests are asymptotically equivalent and will produce comparable chi-squared
values when applied a large sample of rated objects.
