Only core function of the simulation function, always just returns observations. Mostly useful for estimations / optimal design. Has no checks (for speed)!
sim_core(sim_object = NULL, ode, duplicate_t_obs = FALSE, t_init = 0)
Data frame with simulation results
list with design and simulation parameters
ode
allow duplicate t_obs in output? E.g. for optimal design calculations when t_obs = c(0,1,2,2,3). Default is FALSE.
time of initialization of the ODE system. Usually 0.
