%description
Reference distributions that are exact at every sample size, obtained by
conditioning on a statistic sufficient for the nuisance parameter rather
than by appealing to an asymptotic approximation. Two forms of
conditioning are supplied. For a two-way table the row and column totals
are sufficient for the marginal parameters, so conditioning on both
margins leaves the Fisher-Yates law, sampled here exactly by random
permutation of the column labels; statistics include Goodman's
linear-by-linear association and, for nominal rows against an ordinal
column, the dispersion of the row mean scores, whose components are the
group contrasts themselves. A two-table form conditions further on the
total score to cancel a common association parameter, giving a
nuisance-free test that two tables share it. For a linear model under a
null in which the tested structure is absent, a statistic invariant to the
coefficients and the error scale depends on the data only through the
residual direction, which is uniform on the sphere of the residual space;
the reference stays exact when the statistic is maximised over candidate
structures, and so remains valid after a spatial weight matrix has been
chosen by fit. Every replicate draws from its own stream, so results do
not depend on the thread count. The same C sources back the 'Python'
package 'exactcond'.
