extract_parameter_samples function

Extract Parameter Samples from a Stan Model

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

extract_parameter_samples(
  stan_fit,
  data,
  reported_dates,
  imputed_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.
• imputed_dates: A vector of dates to report imputed reports 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.

Returns

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