Selenocysteine data from Jeske et al (2009). For group i, d_i is the dose, y_i+ is the observed number of deaths, n_i is the number of subjects, y_i+/n_i is the empirical death rate, P̂_i is the predicted death rate under the Hill model, E_i is the expected number of deaths (rounded) under the Hill model, and the last column is a measure of model goodness-of-fit.
