We propose a new robust Jarque-Bera (RJB) test utilizing a robust measure of variance. The RJB statistic is asymptotically [chi]22-distributed and has equal or higher power than the JB test for several common alternatives to normality.

After expressing the Fisher information in randomly censored data in terms of hazard rates, we examine the loss of Fisher information under the Koziol-Green random censoring model. Because the same parameter enters both the survival and censoring distributions in this model, the censored data...

We present a modification of a recently proposed test of symmetry about a known center. The new test uses Wilcoxon scores to weigh the runs and has a limiting normal distribution under the null hypothesis. A Monte Carlo study shows that it is more powerful than both the runs and Wilcoxon...
