A simulated data set based on statistics of life expectancy in the US at birth.
lifeexpectA 1,000 rows data frame with three columns:
age: Years lived.
smoke: 0/1 variable equal to 1 if the individual smokes.
female: 0/1 variable equal to 1 if the individual is a female at birth.
The data was generated using official statistics from the CDC and a study of life expectancy of smokers in the US published in the New England Journal of Medicine (see references).
According to the CDC, data from 2020 indicates that the average life expectancy of females in the US is 80.5 years vs 75.1 years for males (which declined with respect to 2019 after COVID hit the US). In Jha et al. (2013), evidence is presented indicating that individuals who smoke have at least ten years left of life expectancy compared to non-smokers.
The parameter estimates for the data generating process where:
An average of life expectancy of 80.1.
Smokers live 10 years less than non-smokers.
Females live 5.4 years longer than males.
