We derive the exact finite sample distribution of the L1-version ofthe Fisz-Cramér-von Mises test statistic (L1-FCvM). We first characterizethe set of all distinct sample p-p plots for two balanced sampleof size n absent ties. Next, we order this set according to the correspondingvalue of...

This paper presents a discussion of overdispersed generalized linear regression models. Commonly used estimates of the unknown dispersion parameter are the Pearson statistic or the modification of Farrington (1996), who proposed a first order linear correction term to Pearson's statistic. We...

Trapezoidal fuzzy numbers have numerous advantages over triangular fuzzy numbers as they have more generalized form. In this paper, two sample statistical test of hypothesis for means in normal population with interval data is given. The decision rules whether to accept or reject the null...
