Approximate number of contingency tables with specified marginal
totals.
Usage
good(x, method = "D", ...)
Arguments
x
An integer-valued matrix (with no NA entries)
method
The method to use; one of A, B, C,
D. See details section
...
Further arguments (notably n), passed to
no.of.boards()
Details
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 NAs.
