fix_parameters: Fix the parameters of a <dist_spec>

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

Fix the parameters of a ⁠<dist_spec>⁠

Description

If the given ⁠<dist_spec>⁠ has any uncertainty, it is removed and the corresponding distribution converted into a fixed one.

Usage

## S3 method for class 'dist_spec'
fix_parameters(x, strategy = c("mean", "sample"), ...)

Arguments

x	A ⁠<dist_spec>⁠
strategy	Character; either "mean" (use the mean estimates of the mean and standard deviation) or "sample" (randomly sample mean and standard deviation from uncertainty given in the ⁠<dist_spec>⁠
...	ignored

Value

A ⁠<dist_spec>⁠ object without uncertainty

Examples

# An uncertain gamma distribution with shape and rate normally distributed
# as Normal(3, 0.5) and Normal(2, 0.5) respectively
dist <- Gamma(
  shape = Normal(3, 0.5),
  rate = Normal(2, 0.5),
  max = 20
)

fix_parameters(dist)
