摘要：
Two shortcomings of the ordinary X2 test for goodness of fit are that it disregards the signs of deviations between observed and expected values and takes no account of the order of those signs. Neyman''s [PSI]2 criterion involves a priori specification of the parameters of the hypothesis to be tested. A test criterion is given which takes into account only the signs of deviations and the order of signs. Tables of the frequency distribution of the criterion are given for 2 to 14 signs. It is shown that this criterion is independent of the X2 test and a combined test is developed. A table of 5% and 1% points of the combined test is shown for 5 to 14 signs of deviations.
