This paper considers the problem of pooling means of two independent random samples from discrete distributions (in particular Poisson and binomial) which can be approximated by normal distributions ...

Abstract: Starting from the Poisson model we present a channel model for optical communications, called the Square Root (SR) Channel, in which the noise is additive Gaussian with constant variance.

Abstract: Traffic overflowing a first-choice trunk group can be approximated accurately by a simple renewal process called an interrupted Poisson process–a Poisson process which is alternately turned ...

Abstract: We consider the situation when the number of claims is unavailable, and a Tweedie’s compound Poisson model is fitted to the observed pure premium. Currently, there are two different models ...

First-order derivatives: n additional function calls are needed. Second-order derivatives based on gradient calls, when the "grd" module is specified (Dennis and Schnabel 1983): n additional gradient ...
