We study the distribution of a test statistic which is known to perform comparably well with other statistics for the same purpose under normality. The statistic we consider is based on Shannon's entropy for a distribution function. We will derive the asymptotic expansion for the distribution of the test statistic based on Shannon's entropy under nonnormality and numerically examine its performance in comparison with the modified likelihood ratio criteria for normal and some nonnormal populations. eng restricted access On testing homogeneity of variances for nonnormal models using entropy journal article
