The data show the number of death notices for women who are 80 years of age or older

Description

The function gives the number of death notices for women who are 80 years of age or older.

Usage

data_death

Arguments

data_death

A vector of (non-negative integer) count values.

Details

The data show the number of death notices for women who are 80 years of age or older, appearing in the London Times on each day for three consecutive years. Recently, they were used by Zhang et al. (2016) and fitted by the zero-and-one inflated Poisson distribution.

Value

data_death gives the number of death notices for women who are 80 years of age or older.
