Check if <epiparameter> or list of <epiparameter> objects contains a distribution and distribution parameters

Check if <epiparameter> or list of <epiparameter> objects contains a distribution and distribution parameters

Usage

is_parameterised(x, ...)

is_parameterized(x, ...)

Arguments

x

An <epiparameter> or list of <epiparameter> objects.

...

dots Extra arguments to be passed to the method.

Value

A single boolean logical for <epiparameter> or vector of logicals equal in length to the list of <epiparameter> objects input. If the <epiparameter> object is missing either a probability distribution or parameters for the probability distribution returns FALSE, otherwise it returns TRUE.

Examples

# parameterised <epiparameter>
ep <- epiparameter(
  disease = "ebola",
  epi_dist = "incubation",
  prob_distribution = "gamma",
  prob_distribution_params = c(shape = 1, scale = 1)
)
#> Citation cannot be created as author, year, journal or title is missing
is_parameterised(ep)
#> [1] TRUE

# unparameterised <epiparameter>
ep <- epiparameter(
  disease = "ebola",
  epi_dist = "incubation"
)
#> Citation cannot be created as author, year, journal or title is missing
#> No adequate summary statistics available to calculate the parameters of the NA distribution
#> Unparameterised <epiparameter> object
is_parameterised(ep)
#> [1] FALSE

# list of <epiparameter>
db <- epiparameter_db()
#> Returning 122 results that match the criteria (99 are parameterised). 
#> Use subset to filter by entry variables or single_epiparameter to return a single entry. 
#> To retrieve the citation for each use the 'get_citation' function
