Data source

The data used in this project originates from Sveriges dödbok, a genealogical database with information about people who have died in Sweden since 1860. Sveriges dödbok is released by Sveriges Släktforskarförbund (The Federation of Swedish Genealogical Societies) and I am grateful to them for allowing me to use the data.

How-to process the data

The code is organized in a set of R-scripts as follows:

• main.R: Contains the code to read data into R and calls a number of other scripts where estimation and plotting are done

• estimateRates.R: Code to estimate hazard rates for all the cohorts

• figure1.R: Generate figure 1 in the manuscript

• figure2.R: Generate figure 2 in the manuscript

• figure3.R: Generate figure 3 in the manuscript

• figure4.R: Generate figure 4 in the manuscript

Example:

To generate the figures do the following:

• clone the repository (git clone https://github.com/aledberg/seasons)

• start R in the cloned directory

• at the R prompt execute source("main.R")
