The aim of this paper is to relate and extend some recent work on chi-square goodness-of-fit tests. There is no discussion of any problems which are specifically associated with more than one ...

A statistical test that allows one to determine whether observed quantities of a specific characteristic differed from the expected value purely by chance.

Results are reported of a sampling experiment on the adequacy of the chi-squared approximation to the usual goodness-of-fit statistic. The expected cell frequencies are taken to be equal. There is ...
