pomp (version 0.38-2)

dacca: Model of cholera transmission for historic Bengal.

Description

dacca is a pomp object containing census and cholera mortality data from the Dacca district of the former British province of Bengal over the years 1891 to 1940 together with a stochastic differential equation transmission model. The model is that of King et al. (2008). It also has the MLE for the SIRS model with seasonal reservoir.
