llik.cb: Negative log-likelihood function for the chain-binomial model

In epimdr: Functions and Data for "Epidemics: Models and Data in R"

Description

Negative log-likelihood function for the chain-binomial model

Usage

llik.cb(S0, beta, I)

Arguments

S0	a scalar with value for S0
beta	a scalar with value for beta
I	a vector incidence aggregated at serial interval

Value

the negative log-likelhood for the model

Examples

twoweek=rep(1:15, each=2)
niamey_cases1=sapply(split(niamey$cases_1[1:30], twoweek), sum)
llik.cb(S0=6500, beta=23, I=niamey_cases1)
