%description
Computes experimental designs for a two-arm experiment with covariates via
a number of methods: (0) complete randomization and randomization with
forced-balance, (1) Greedily optimizing a balance objective function via
pairwise switching. This optimization provides lower variance for the
treatment effect estimator (and higher power) while preserving a design
that is close to complete randomization. We return all iterations of the
designs for use in a permutation test, (2) The second is via numerical
optimization (via 'gurobi' which must be installed, see
<https://www.gurobi.com/documentation/9.1/quickstart_windows/r_ins_the_r_package.html>)
a la Bertsimas and Kallus, (3) rerandomization, (4) Karp's method for one
covariate, (5) exhaustive enumeration to find the optimal solution (only
for small sample sizes), (6) Binary pair matching using the 'nbpMatching'
library, (7) Binary pair matching plus design number (1) to further
optimize balance, (8) Binary pair matching plus design number (3) to
further optimize balance, (9) Hadamard designs, (10) Simultaneous Multiple
Kernels. In (1-9) we allow for three objective functions: Mahalanobis
distance, Sum of absolute differences standardized and Kernel distances
via the 'kernlab' library. This package is the result of a stream of
research that can be found in Krieger, A, Azriel, D and Kapelner, A

Experimental Design by Hybridizing Binary Matching with Imbalance
Optimization" (2021) <arXiv:2012.03330>.
