t-distribution. Statistics & Probability Letters 83, 70–77] proposed a generalization of Student’s
t distribution to account for negative degrees of freedom. Here, an alternative distribution
that has simpler mathematical properties is discussed. Several advantages are
established for using the alternative distribution over Papastathopoulos and Tawn’s generalization.

The propose method is illustrated with some data and the test statistics is shown to perform at least in terms of power and efficiency. The method also enables the easy isolation of any ties in the data and the estimation of their probabilities of occurrence
