ssd_fit_bcanz

Fits distributions using settings adopted by
BC, Canada, Australia and New Zealand for official guidelines.

Species sensitivity distributions are cumulative probability
distributions which are fitted to toxicity concentrations for
different species as described by Posthuma et al.(2001)
<isbn:9781566705783>. The ssdtools package uses Maximum Likelihood to
fit distributions such as the gamma, log-logistic, log-normal and
Weibull to censored and/or weighted data. Multiple distributions can
be averaged using Akaike Information Criteria. Confidence intervals
on hazard concentrations and proportions are produced by parametric
bootstrapping.
