Species Sensitivity Distributions.

Species sensitivity distributions are cumulative probability distributions which are fitted to toxicity concentrations for multiple species. The ssdtools package uses Maximum Likelihood to fit log-normal, log-logistic, log-Gumbel, Gompertz, gamma or Weibull distributions. Multiple distributions can be averaged using Information Criteria. Confidence intervals can be calculated for the fitted cumulative distribution function or specific hazard concentrations (percentiles). Confidence intervals are currently produced by bootstrapping.
