Smallpox1972: Data on the 1972 smallpox epidemic in Kosovo

Description

This data set gives

1/ the daily incidence of onset of symptoms in Kosovo during the 1972 smallpox epidemic (see source and references),

2/ the discrete daily distribution of the serial interval for smallpox, assuming a shifted Gamma distribution with mean 22.4 days, standard deviation 6.1 days and shift 1 day (see references).

Usage

Smallpox1972

Format

A list of two elements:

1/ "Incidence": a vector containing 57 days of observation,

2/ "SI.Distr": a vector containing a set of 46 probabilities.

Examples

# NOT RUN {
		## load data on smallpox in Kosovo in 1972
		data("Smallpox1972")

		## estimate the instantaneous reproduction number (method "NonParametricSI")
		EstimateR(Smallpox1972$Incidence, T.Start=27:51, T.End=33:57, method="NonParametricSI", 
			SI.Distr=Smallpox1972$SI.Distr, plot=TRUE, leg.pos=xy.coords(1,15))
		# the second plot produced shows, at each each day, 
		# the estimate of the instantaneous reproduction number over the 7-day window finishing on that day.
