Simulate the Malaria Model Over Time — sim

Runs a stochastic malaria transmission model using an odin-generated model object, storing state outputs across multiple time steps and particles.

Usage

sim_mod(odin_mod, pars, time_start, n_particles, sim_time)

Arguments

odin_mod: An odin model object (usually created with odin::odin()), representing the compiled malaria model.
pars: A named list of parameters to pass to the model.
time_start: Numeric value specifying the starting time (e.g., 0).
n_particles: Integer; number of particles used in the stochastic simulation (i.e., number of replicate simulations).
sim_time: Integer; total number of time steps (days) to simulate.

Value

A list with two elements:

x: A 3D array of simulation results with dimensions [state, particle, time].
model: The odin model object after simulation (can be used to inspect internals).

Details

The model is initialized once using the odin_mod$new() constructor, and then model$run(t) is called at each time step t to advance the simulation.

Examples

if (FALSE) { # \dontrun{
mod <- odin::odin("malaria_model.R")
results <- sim_mod(mod, pars = list(beta = 0.2), time_start = 0, n_particles = 10, sim_time = 100)
} # }
