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
log-normal log-normal mixture. Multiple distributions can be averaged
using Akaike Information Criteria. Confidence intervals on hazard
concentrations and proportions are produced by bootstrapping.
