A P-P plot compares the empirical cumulative distribution function (ecdf) of a variable with a specified theoretical cumulative distribution function F(·). The ecdf, denoted by F n (x), is defined as ...

With the current interest in copula methods, and fat-tailed or other non-normal distributions, it is appropriate to investigate technologies for managing marginal distributions of interest. We explore ...

In this article we review two historical approximations to the Poisson and binomial cumulative distribution functions (CDFs); that is, the Wilson—Hilferty and Camp—Paulson approximations. Both of ...

One estimate of a symmetric location cumulative distribution function F(x - θ) is obtained by symmetrizing the sample cumulative distribution function with respect to the estimated centre of symmetry ...
