Abstract
|
A recent paper by Leipnik and Pearce introduced
the gamma Weibull distribution. One of the main
properties given is its characteristic function,
which is expressed as an infinite sum. In this
note, we provide a simpler representation in
terms of the well-known hypergeometric functions
in some special cases. We also derive expressions
for moments of the distribution.
