The Beta-Hyperbolic Secant Distribution
The shape of a probability distribution is often summarized by the distribution’s skewness and kurtosis. Starting from a symmetric “parent” density f on the real line, we can modify its shape (i.e. introduce skewness and in-/decrease kurtosis) if f is appropriately weighted. In particular, every density w on the interval (0, 1) is a specific weighting function. Within this work, we follow up a ...

متن کاملTwo-sample scale rank procedures optimal for the generalized secant hyperbolic distribution
There are many linear rank tests for the two-sample dispersion problem presented in literature. However just a few of them, the simplest ones, are commonly used. These common tests are not efficient for many practical distributions and thus other simple tests need to be developed to serve a wider range of distributions. The generalized secant hyperbolic distribution, proposed by Vaughan in [9],...

متن کاملOn random variate generation for the generalized hyperbolic secant distributions
Natural exponential families of distributions have probability mass functions of the form [exp(Ox)]#(dx) where # is a given measure, and 0 > 0 is a parameter. When we compute the mean and the variance, and force the variance to be a quadratic function of the mean as 0 is varied, the number of families becomes severely restricted. Morris (1982) showed that there are in fact only six natural expo...
