Krippendorff's alpha in MATLAB
function alpha=kriAlpha(data,scale)
% alpha=kriAlpha(data,scale)
% calculates Krippendorff's Alpha as a measure of inter-rater agreement
% data: rate matrix, each row is a rater or coder, each column is a case
% scale: level of measurement, supported are 'nominal', 'ordinal', 'interval'
% missing values have to be coded as NaN or inf
