Hi all,

I’d like to announce the debut of the “Online Kappa Calculator.” It calculates free-marginal and fixed-marginal kappa–a chance-adjusted measure of interrater agreement–for any number of cases, categories, or raters. Roman and Nikko will appreciate this; now we don’t have to do these calculations the hard way!

Thanks to Walubengo M. Singoro for his fantastic programming work on this.

I’m going on vacation to the States tomorrow. If you have any comments, I’ll get back to you in a few weeks. Is anyone else interested in creating a collection of calculators for obscure, but intensely useful, statistics? I have ideas for many student programming projects along this line.
