See Table 8.20 for another rainbow trout ELS study.
Evaluate the two controls for last day of hatching and decide whether to
combine them for further analysis or use only one control group. Defend your
choice. Then analyze last day of hatch, both for NOEC using the
Jonckheere–Terpstra test and from a Poisson errors GLMM model. If possible, fit
a Poisson errors regression model and estimate EC10. Repeat the above treating
day 36 as a right‐censored observation.
