The diagonal natural exponential families (NEFs) on [real]r were defined and classified recently by Bar-Lev et al. (1994). In this paper, we apply explicit formulas for the Mehler kernels of certain bivariate diagonal NEF classes to develop the total positivity properties of these NEFs and ...

Series of new characterizations by zero regression properties are derived for the distributions in the class of natural exponential families with power variance functions. Such a class of distributions has been introduced in Bar-Lev and Enis (1986) in the context of an investigation of reproductible...
2. Let $a$ and $b$ be two nonzero constants. Describe the difference between $g(x) = ax + b$ and its parent function. What is the domain and range of $g(x)$? Open Problem Solutions 1. The parent function of $f(x)$ is $y = x^2$. This means that $f(x)$ has been tr...
The discretized T-Xθ family provided many sub-families and sub-models. In addition, eight real data sets are utilized to demonstrate the flexibility of the proposed continuous and discrete family’s multiple sub models. Similar content being viewed by others Truncated Weibull–exponential ...
We present two families of explicit and implicit BDF formulas, capable of the exact integration (with only round-off errors) of differential equations whose solutions belong to the space generated by the linear combinations of exponential of matrices, products of the exponentials by polynomials and ...
The paper contains various results about quadratic twists of elliptic curves. The emphasis is not so much on a general theory but on the computation of various examples. In the first section the authors give criteria for the Selmer group of a twist to be finite, or at least suitably bounded...
