ad_crit Criterion function for ad_halt.
ad_halt A univariate halting test using the Anderson-Darling test (kSamples::ad.test).
apply_crit Returns smallest halting_test() / thresh ratio, or zero if less than 1.
check_subspaces_for_group_size_setup Searches over all possible subspaces for specified group size setup.
combine_ratios Combines matched group candidate with current best one.
create_Cartesian_iterable Creates Cartesian product of iterators.
create_halting_test Creates halt test from multiple tests.
create_subject_subspace_using_LDA Creates ordered subspace of subject candidates for removal, using LDA.
decrease_group_sizes Creates all group sizes by reducing one group in all rows of grpsizes.
estimate_exhaustive Estimates the maximum number of cases to be checked during exhaustive search.
get_human_readable Returns human readable format for number of seconds.
get_param Gets parameter value for ldamatch.

ks_crit Criterion function for ks_halt.
ks_halt A univariate halting test using the Kolmogorov-Smirnov Test (ks.test).
ldamatch Creates a matched group via backward selection.
search_exhaustive Searches the space backwards, prefering more subjects and better ratios. While the search is done in parallel, the search space is enormous and so it can be very slow in the worst case. It is perhaps most useful as a tool to study other matching procedures.
search_heuristic At each vertex of the search graph, this takes a step which moves the proportions of conditions in the subspace closer to the desired (or sample) proportions.
search_montecarlo Searches for a subset satisfying the test by randomly selecting subspaces of decreasing size.
set_param Sets parameters for ldamatch.
t_crit Criterion function for ad_halt.
t_halt A univariate halting test using the t-test (t.test).
U_crit Criterion function for U_halt.
U_halt A univariate halting test using the Wilcoxon test (wilcox.test).
wilks_halt A multivariate halting test (appropriate when nlevels(condition) > 2)).
