ssd_hc_bcanz: BCANZ Hazard Concentrations

In ssdtools: Species Sensitivity Distributions

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 required 10,000 iterations.

Usage

ssd_hc_bcanz(x, nboot = 10000, delta = 10, min_pboot = 0.9)

Arguments

x	The object.
nboot	A count of the number of bootstrap samples to use to estimate the se and confidence limits. A value of 10000 is recommended for official guidelines.
delta	A non-negative number specifying the maximum absolute Akaike Information-theoretic Criterion difference cutoff. Distributions with an absolute difference from the best model greater than the cutoff are excluded.
min_pboot	A number of the minimum proportion of bootstrap samples that must successfully fit in the sense of returning a likelihood.

Value

A tibble of corresponding hazard concentrations.
