dichromate

Survival data set of chronic laboratory toxicity tests with
Daphnia magna freshwater invertebrate exposed to six concentrations
of one oxidizing agent (potassium dichromate) during 21 days. Six
concentrations were tested with one replicate of 50 organisms per concentration.
Survival is monitored at 10 time points.

Advanced methods for a valuable quantitative environmental risk
assessment using Bayesian inference of survival and reproduction Data. Among
others, it facilitates Bayesian inference of the general unified
threshold model of survival (GUTS). See our companion paper
