Abstract |
A location-dispersion test f o r 2 x k contingency, tables is proposed. The asymptotic distributions of the proposed test are obtained both under the null and alternative hypotheses, and also its powe...r and efficiency are studied. The proposed test is compared with several other chi-squared tests by Monte Carlo studies and it is shown that the test is superior to Pearson's chi-squared test, Nair's location and dispersion tests and to the cumulative chi-squared test in many cases.show more
