Incidence estimation from prevalence of a chronic disease (without remission, without excess mortality)

The script comprises:
1) a data set of aggregated data (cases and population stratified by age) from two cross-sections about a hypothetical chronic disease motivated by type 1 diabetes in the SEARCH study

2) an algorithm programmed in the statistical software R (The R Foundation for Statistical Computing) to estimate the age-specific incidence rate from the prevalence data given in 1) using the assumptions that is no remission (no cure) and no excess mortality

Important note: the data in 1) are mock-up data, which are only given to demonstrate the methodological approach described in 2). These data are not intended for any other purpose.
