Limit Distributions of Random Sums of Z+-Valued Random Variables

S. Satheesh; E. Sandhya; T. Lovely Abraham

In this article, we formulate a transfer theorem in terms of probability generating functions and discuss two approaches to limit distributions of random sums of Z +-valued random variables. We then develop Z +-valued N-ID and ϕ-ID laws.

On distribution functions with completely monotone derivative

E. Sandhya; S. Satheesh

A necessary and sufficient condition for the existence of the mean of distributions with completely monotone derivative is given. Distributions with completely monotone hazard rate are identified. Limit distributions of order statistics in a sample from F(x) which has completely monotone derivative is discussed.
