Extracts posterior samples to use to initialise a full model fit. This may be useful
for certain data sets where the sampler gets stuck or cannot easily be initialised.
regional_epinow() this option can be
engaged by setting
stan_opts(init_fit = <stanfit>).
This implementation is based on the approach taken in epidemia authored by James Scott.
extract_inits(fit, current_inits, exclude_list = NULL, samples = 50)
A stanfit object
A function that returns a list of initial conditions (such as
create_initial_conditions()). Only used in
exclude_list is specified.
A character vector of parameters to not initialise from the fit
object, defaulting to
Numeric, defaults to 50. Number of posterior samples.
A function that when called returns a set of initial conditions as a named list.
