Subject
Summary:

A technology for hand calculating the degree of observer agreement using log linear models is discussed. A coefficient of agreement may be calculated which describes the magnitude of observer agreement as the estimated probability, under a quasi-independence model, that different observer responses will agree. Procedures and formulas for measuring the probability of agreement for one or more response categories within a larger set are also available. Finally, systematic disagreement among observers may also be examined with the available technology.
