Functions are provided that implement the use of the Fieller's formula methodology, for calculating a confidence interval for a ratio of (possibly, correlated) means. See Fieller (1954) <doi:10.1111/j.2517-6161.1954.tb00159.x>. Here, the application of primary interest is to studies of insect mortality response to increasing doses of a fumigant, or, e.g., to time in coolstorage. The formula is used to calculate a confidence interval for the dose or time required to achieve a specified mortality proportion, commonly 0.5 or 0.99. A vignette demonstrates link functions that may be considered, and alternative choices of error family. Note in particular the beta-binomial error family.
