WebThe test statistic is the ratio of two variance estimators, namely, the sample variance and the moments estimator obtained by Villasenor and Gonzalez-Estrada (2015), which is the product of the sample mean of X and the sample covariance of X and log (X). The asymptotic null distribution of the test statistic is used to approximate p-values.
