elephant: Age and mating success for Elephants

In gpk: 100 Data Sets for Statistics Education

Description

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.
