The Statas kap command is used to estimate the Inter-Rater agreement and can handle situations where the two variables have the same categories and other situations where they do not, as is the case above. Here`s an example. Kappa goes from zero (no deal) to one (perfect agreement). Stata proposes the following guidelines from Landis-Koch (1977) on the level of compliance of a certain kappa value: the calculation of the Interrater agreement with Stata is carried out with orders from Kappa and Cape Town. Which of the two commands you use depends on how your data is entered. However, after this initial difference, both commands have the same syntax.

Let`s take an example where two graduates were asked to evaluate 12 films on a scale of 1-3. One counselor used the three possible scores while evaluating the films, while the other student did not like any of the films and therefore valued them all as a 1 or a 2. Thus, the area of partitions is not the same for the two advisors.

Suppose we want to compare two advisors to a Kappa statistic, but the advisors have different points. This situation occurs most often where one of the advisors did not use the same score as the other advisors.
