hi
i have a two by two table where the kappa statistic is calculated
some of the tables have very small numbers (e.g. 1,2,3) or even 0 in some
of the cells
is there a minimum number that must be in each of the cells for the kappa
statistic to be valid
are the tables with a 0 entry in one of the cells a different case from
tables that may have the very small numbers
any help greatly appreciated
regards
ann
