ssd_hc_bcanz: BCANZ Hazard Concentrations

Description

Gets hazard concentrations with confidence intervals that protect 1, 5, 10 and 20% of species using settings adopted by BC, Canada, Australia and New Zealand for official guidelines. This function can take several minutes to run with recommended 10,000 iterations.

Usage

ssd_hc_bcanz(
  x,
  proportion = c(0.01, 0.05, 0.1, 0.2),
  ...,
  average = TRUE,
  ci = FALSE,
  nboot = 10000,
  min_pboot = 0.8
)

Value

A tibble of corresponding hazard concentrations.

Arguments

x

The object.

proportion

A numeric vector of proportion values to estimate hazard concentrations for.

...

Unused.

average

A flag specifying whether to provide model averaged values as opposed to a value for each distribution.

ci

A flag specifying whether to estimate confidence intervals (by bootstrapping).

nboot

A count of the number of bootstrap samples to use to estimate the confidence limits. A value of 10,000 is recommended for official guidelines.

min_pboot

A number between 0 and 1 of the minimum proportion of bootstrap samples that must successfully fit (return a likelihood) to report the confidence intervals.
