| Abstract | Based on the idea of McCulloch (1985) we introduced new modified chi-squared test, 2 n S , for bivariate circular normality. We compare the power of 2 n S with that for other modified chi-squared tests and with the well-known AndersonDarling 2 A , Cramer-von Mises 2 W , and Mardia?s (1970) tests. The results reveal two advantages of 2 n S statistic over abovementioned tests: while possessing a comparable power, the 2 n S does not require simulation of critical values to define rejection region even for small samples, and removes requirement for defining the optimal number of grouping intervals. |
