2001-02-24 Thread Jan
I have two samples (size about 50) from discrete distributions. Does anybody know some nonparametric tests to check whether the two samples come from the same distribution? For continuous distributions there is Kolmogorov-Smirnov two sample test but I need similar test for discrete case. Jan

Interesting point. Yes, if the Ss do something other than a random guess the binomial model would be violated. The question then becomes what would they do if they are uncertain? I suspect that they would fall back on visual inspection...which piece appears to be different than the others (les
