In seabbs/epinowcast: Flexible Hierarchical Nowcasting

Update initial values for model fitting

Description

This function updates the initial values for model fitting based on the specified initialization method.

Usage

update_inits(
  data,
  model,
  init,
  init_method = c("prior", "pathfinder"),
  init_method_args = list(),
  ...
)

Arguments

data	A list of data as produced by model modules (for example enw_expectation(), enw_obs(), etc.) and as required for use the model being used.
model	A cmdstanr model object as loaded by enw_model() or as supplied by the user.
init	A list of initial values or a function to generate initial values. If not provided, the model will attempt to generate initial values
init_method	The method to use for initializing the model. Defaults to "prior" which samples initial values from the prior. "pathfinder", which uses the pathfinder algorithm (enw_pathfinder()) to initialize the model.
init_method_args	A list of additional arguments to pass to the initialization method.
...	Additional arguments passed to initialization methods.

Value

A list containing updated initial values and method-specific output.
