Examples

SI_model <- odemodel(
    name = "SI",
    model = list(
        S ~ - beta*S*I/N,
        I ~ beta*S*I/N - gamma*I
    ),
    observation = list(
        susceptible ~ dnorm(mean=S, sd=sigma1),
        infected ~ dnorm(mean=I, sd=sigma2)
    ),
    initial = list(
        S ~ N * (1 - i0),
        I ~ N * i0
    ),
    par = c("beta", "gamma", "N", "i0", "sigma1", "sigma2"),
    link = c(i0="logit")
)
