fit_stem | R Documentation |
Fit a stochastic epidemic model using the linear noise approximation or ordinary differential equations to approximate the latent epidemic process.
fit_stem( stem_object, method, mcmc_kern, iterations, initialization_attempts = 500, ess_warmup = 50, thinning_interval = 100, return_adapt_rec = FALSE, return_ess_rec = FALSE, print_progress = 0, status_filename = NULL )
stem_object |
a stochastic epidemic model object containing the dataset, model dynamics, and measurement process. |
method |
either "lna" or "ode". |
mcmc_kern |
MCMC transition kernel generated by a call to the
|
iterations |
number of iterations |
initialization_attempts |
number of initialization attempts |
ess_warmup |
number of preliminary ESS iterations for the LNA, initial conditions, and time varying parameters prior to starting MCMC |
thinning_interval |
thinning interval for posterior samples, defaults to saving every 100th sample |
return_adapt_rec |
should the MCMC samples be returned during adaptation? defaults to FALSE. |
return_ess_rec |
should elliptical slice sampling steps and angles be returned? defaults to FALSE |
print_progress |
interval at which to print progress to a text file. If 0 (default) progress is not printed. |
status_filename |
string to pre-append to status files, defaults to LNA or ODE depending on the method used. |
list with posterior samples for the parameters and the latent process, along with MCMC diagnostics.
