malesINfirst12

The number of male children among the first 12 children of family size 13 in 6115 families taken from the hospital records in the nineteenth century Saxony (Lindsey (1995), p.59). The thirteenth child is ignored to assuage the effect of families non-randomly stopping when a desired gender is reached.

Functions are provided that implement the
use of the Fieller's formula methodology, for
calculating a confidence interval for a ratio of
(commonly, correlated) means. See Fieller (1954)
<doi:10.1111/j.2517-6161.1954.tb00159.x>. Here,
the application of primary interest is to studies
of<c2><a0>insect mortality response to<c2><a0>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. Vignettes demonstrate link functions
that may be considered, checks on fitted models,
and alternative choices of error family. Note
in particular the betabinomial error family.
