predict.fitburrlioz: Predict Hazard Concentrations of fitburrlioz Object

Description

A wrapper on ssd_hc() that by default calculates all hazard concentrations from 1 to 99%.

Usage

# S3 method for fitburrlioz
predict(
  object,
  percent,
  proportion = 1:99/100,
  ci = FALSE,
  level = 0.95,
  nboot = 1000,
  min_pboot = 0.95,
  parametric = TRUE,
  ...
)

Arguments

object

The object.

percent

A numeric vector of percent values to estimate hazard concentrations for. Deprecated for proportion = 0.05.

proportion

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

ci

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

level

A number between 0 and 1 of the confidence level of the interval.

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.

parametric

A flag specifying whether to perform parametric bootstrapping as opposed to non-parametrically resampling the original data with replacement.

...

Unused.

Details

It is useful for plotting purposes.
