Simulate the Stochastic Ricker Model
1 | sim.Ricker(N0, param, Tmax, nsim, method=c("normal","resample"), resids=NULL)
|
N0 |
Starting population size |
param |
Vector of parameters for the model. First element is mu, second is
K, and the third (used only if |
Tmax |
Number of years to simulate |
nsim |
Number of replicate simulations |
method |
Treat epsilon as normally distributed random numbers ( |
resids |
The residuals from which to resample to simulate epsilon.
Used only if |
This is pretty straightforward.
A matrix with Tmax
rows and nsim
columns. Each column is the time
series from a replicate simulation.
