posterior_latent {epidemia}R Documentation

Generic function for getting posterior draws of a specified latent sequence

Description

Draws samples from one of a number of unobserved time series using the posterior parameter draws from the passed object. Can retrieve posterior estimate of the reproduction number over time (unadjusted or adjusted), the daily new infections, or the total "infectiousness" of the population over time.

Usage

posterior_latent(object, ...)

## S3 method for class 'epimodel'
posterior_latent(
  object,
  newdata = NULL,
  series = c("Rt", "Rt_unadj", "infections"),
  draws = NULL,
  seed = NULL,
  ...
)

Arguments

object

A fitted model object returned by epim. See epimodel-objects.

...

Not used.

newdata

If provided, the original data used in object is overridden. Useful both for counterfactual and prediction analysis

series

Type of latent series to return.

draws

Number of posterior draws to use. Defaults to the number of parameter draws in the fitted model.

seed

An optional seed.

Value

A named list with draws of the series, and vectors giving the corresponding dates and population.
