mortAAR
-------
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](https://books.google.de/books?id=nG5FoO_becAC&lpg=PA27&ots=LG0b_xrx6O&dq=life%20table%20archaeology&pg=PA27#v=onepage&q&f=false) 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:
- Ease and flexibility of input (different kinds of customization and grouping)
- Sophisticated means of computation (exploding of age ranges, separation factor for average lived years)
- Comprehensiveness of output (life tables for all groups specified, plots for the most important measures, relative population calculation)
