With mortAAR
you can calculate a life table based on archaeological demographic data. You just need the number of people of a certain age, but you can also use single individual data. mortAAR
allows to separate the data according to sex/location/epoch or any other grouping variable.
What is a life table [aka discrete time survival analysis]? According to Chamberlain it is a
"(...) mathematical device for representing the mortality experience of a population and for exploring the effects on survivorship of age-specific probabilities of death. One reason why life tables have been ubiquitous in demography is that mortality cannot easily be modelled as a single equation or continuous function of age."
To our knowledge as of writing, a simple to use and easily accessible tool to calculate and create archaeological life tables has been lacking. That is why we sat down and put mortAAR
for R together. We hope it will be of use for archaeologists world-wide.
In our view, mortAAR
shines in the following areas:
