dist_spec: Specify a distribution.

In EpiNow2: Estimate Real-Time Case Counts and Time-Varying Epidemiological Parameters

Specify a distribution.

Description

This function is deprecated as a user-facing function (while its functionality is still used internally). Construct distributions using the corresponding distribution function such as Gamma(), LogNormal(), Normal() or Fixed() instead.

Usage

dist_spec(
  distribution = c("lognormal", "normal", "gamma", "fixed", "empty"),
  params_mean = numeric(0),
  params_sd = numeric(0),
  max = Inf,
  pmf = numeric(0),
  fixed = FALSE
)

Arguments

distribution	Character, defaults to "lognormal". The (discretised) distribution to be used. Can be "lognormal", "gamma", "normal" or "fixed". The corresponding parameters (defined in natural_params()) are passed as params_mean, and their uncertainty as params_sd.
params_mean	Numeric. Central values of the parameters of the distribution as defined in [natural_params().
params_sd	Numeric. Standard deviations of the parameters of the distribution as defined in [natural_params().
max	Numeric, maximum value of the distribution. The distribution will be truncated at this value. Default: Inf, i.e. no maximum.
pmf	Numeric, a vector of values that represent the (nonparametric) probability mass function of the delay (starting with 0); defaults to an empty vector corresponding to a parametric specification of the distribution (using params_mean, and params_sd.
fixed	Deprecated, use fix_parameters() instead.

Value

A list of distribution options.
