ricker: Ricker model with Poisson observations.

Description Details See Also Examples

Description

ricker is a pomp object encoding a stochastic Ricker model with Poisson measurement error.

Details

The state process is N[t+1] = r N[t] exp(-N[t]+e[t]), where the e[t] are i.i.d. normal random deviates with zero mean and variance sigma^2. The observed variables y[t] are distributed as Poisson(phi N[t]).
