Extract Parameter Samples from a Stan Model

Description

Extracts a custom set of parameters from a stan object and adds stratification and dates where appropriate.

Usage

extract_parameter_samples(
  stan_fit,
  data,
  reported_dates,
  reported_inf_dates,
  drop_length_1 = FALSE,
  merge = FALSE
)

Arguments

stan_fit	A ⁠<stanfit>⁠ or ⁠<CmdStanMCMC>⁠ object as returned by fit_model().
data	A list of the data supplied to the fit_model() call.
reported_dates	A vector of dates to report estimates for.
reported_inf_dates	A vector of dates to report infection estimates for.
drop_length_1	Logical; whether the first dimension should be dropped if it is off length 1; this is necessary when processing simulation results.
merge	if TRUE, merge samples and data so that parameters can be extracted from data.

Value

A list of ⁠<data.frame>⁠'s each containing the posterior of a parameter
