measles: Historical childhood disease incidence data

In pomp: Statistical Inference for Partially Observed Markov Processes

Description

LondonYorke is a data frame containing the monthly number of reported cases of chickenpox, measles, and mumps from two American cities (Baltimore and New York) in the mid-20th century (1928–1972).

ewmeas and ewcitmeas are data frames containing weekly reported cases of measles in England and Wales. ewmeas records the total measles reports for the whole country, 1948–1966. One questionable data point has been replaced with an NA. ewcitmeas records the incidence in seven English cities 1948–1987. These data were kindly provided by Ben Bolker, who writes: “Most of these data have been manually entered from published records by various people, and are prone to errors at several levels. All data are provided as is; use at your own risk.”
