All formulae and terminology taken from Good 1976. The letters A-D are from the approximations given on pages 1167 and 1168.
Note This function will accept matrices with any NA
entries, but a warning is given. The number of permissable boards
will be less than the number of permissible contingency tables
considered by Good.
The approximations are intended to provide rough-and-ready upper
bounds for boards that have a few NA
s.
Method “A” is the exact answer, given by
no.of.boards()
. Do not use this on large matrices!
Methods “B”, “C”, and “D” give (according to Good) increasingly accurate approximations to the exact answer.
