kappam_vanbelle

This function expands upon Cohen's and Fleiss' Kappa as measures for
interrater agreement while taking into account the heterogeneity within each
group.

Estimate agreement of a group of raters with a gold standard rating
on a nominal scale. For a single gold standard rater the average pairwise
agreement of raters with this gold standard is provided. For a group of (gold
standard) raters the approach of S. Vanbelle, A. Albert (2009)
<doi:10.1007/s11336-009-9116-1> is implemented. Bias and standard error are
estimated via delete-1 jackknife.
