Usage

posterior_coverage(
  object,
  type,
  newdata = NULL,
  groups = NULL,
  levels = c(50, 95)
)

Arguments

object

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

type

A string specifying the name of the observations to plot. This should match one of the names of the response variables in the obs argument used int the call to epim.

newdata

If provided, the original data used in object is overridden. Useful for forecasting
