states: make country-year/month/day panel data that is consistent with the COW or Gleditsch & Ward lists of independent states. I use these bare-bones panels as templates to which other data have to conform when merging IR datasets.
spduration: implementation of Weibull and Log-logistic split-population duration models. These models are designed for instances when you want to model the duration to some event but the population of cases consists of a mixture that includes some proportion of cases that will not experience the event at all, e.g. at what age teenagers start smoking, criminal recidivism among former prisoners, and cancer relapse.
