ssd_plot_cf

ssd_cfplot

Plots a Cullen and Frey graph of the skewness and kurtosis
for non-censored data.

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.
