Fit Burrlioz Distributions

Source: R/fit-burrlioz.R
ssd_fit_burrlioz.Rd

Fits 'burrIII3' distribution. If shape1 parameter is at boundary returns 'lgumbel' (which is equivalent to inverse Weibull). Else if shape2 parameter is at a boundary returns 'invpareto'. Otherwise returns 'burrIII3'

Usage

ssd_fit_burrlioz(
  data,
  left = "Conc",
  rescale = FALSE,
  control = list(),
  silent = FALSE
)

Arguments

data

A data frame.

left

A string of the column in data with the concentrations.

rescale

A flag specifying whether to rescale concentration values by dividing by the geometric mean of the minimum and maximum positive finite values.

control

A list of control parameters passed to stats::optim().

silent

A flag indicating whether fits should fail silently.

Value

An object of class fitdists.
