epiparameter (version 0.4.1)

family.epiparameter: Family method for the <epiparameter> class

Description

The family() function is used to extract the distribution names from objects from {distributional} and {distcrete}. This method provides the same interface for <epiparameter> objects to give consistent output irrespective of the internal distribution class.

Usage

# S3 method for epiparameter
family(object, ..., base_dist = FALSE)

Value

A character string with the name of the distribution, or NA when the <epiparameter> object is unparameterised.

Arguments

object

An <epiparameter> object.

...

further arguments passed to methods.

base_dist

A boolean logical for whether to return the name of a transformed distribution (e.g. "mixture" or "truncated") or the underlying distribution type (e.g. "gamma" or "lnorm"). Default is FALSE.

Examples

# example with continuous distribution
ep <- epiparameter(
  disease = "ebola",
  epi_name = "incubation_period",
  prob_distribution = create_prob_distribution(
    prob_distribution = "gamma",
    prob_distribution_params = c(shape = 1, scale = 1)
  )
)
family(ep)

# example with discretised distribution
ep <- epiparameter(
  disease = "ebola",
  epi_name = "incubation_period",
  prob_distribution = create_prob_distribution(
    prob_distribution = "lnorm",
    prob_distribution_params = c(meanlog = 1, sdlog = 1),
    discretise = TRUE
  )
)
family(ep)
