  Some new survival distributions are introduced based on a generalised
exponential function. This class of distributions includes heavy-tailed
generalisations of exponential, Weibull and gamma distributions. Properties of
the distributions are described, and R code is available for computation of
pdf, quantiles, inverse quantiles, random numbers, etc. A use of these
distributions for robust inference is suggested, and this is exemplified with a
Monte-Carlo study.
