elephant


Elephants reach maturity at about 14 years of age. But they have to compete with all adult males for mating opportunity. Females are generally more receptive to larger males. Size of an elephant increases as age increases. Hence it is expected that generally the number of matings should increase with age. Is there an optimal age after which the success rate does not rise further? Mating is a rare event and hence may follow a Poisson distribution.

Collection of datasets as prepared by Profs. A.P. Gore, S.A. Paranjape, and M.B. Kulkarni of Department of Statistics, Poona University, India. With their permission, first letter of their names forms the name of this package, the package has been built by me and made available for the benefit of R users. This collection requires a rich class of models and can be a very useful building block for a beginner.
