Nonparametric comparison of two histograms.
Scholz and Stephens (1987, Journal of the American Statistical Association 82, 918-924) proposed a nonparametric k-sample Anderson-Darling statistic for grouped data. This note demonstrates that a partition-of-chi 2 method may give a more powerful nonparametric test, particularly when alternatives other than location shift are important. A taste-test example provides motivation.
