%description
Statistical methods to match feature vectors between multiple datasets in
a one-to-one fashion. Given a fixed number of classes/distributions, for
each unit, exactly one vector of each class is observed without label. The
goal is to label the feature vectors using each label exactly once so to
produce the best match across datasets, e.g. by minimizing the variability
within classes. Statistical solutions based on empirical loss functions
and probabilistic modeling are provided. The 'Gurobi' software and its 'R'
interface package are required for one of the package functions
(match.2x()) and can be obtained at <https://www.gurobi.com/> (free
