I often use the following function

and, less often,

The reason that there is no value for level "A" of treatment is

I've been having trouble making sense of the drc results for my binomial
response toxicity data. Firstly, the standard errors are far too large for
how well the data fit the log-logistic model, particularly compared to other
methods of LC50 estimation (e.g. probit and trimmed spearman-karber).
