%description
Estimates RxC transfer matrices from aggregated marginal data using a
two-stage (GME+IPF) information-theoretic approach within a two-step
(global+local) estimation procedure. The resulting matrices are consistent
with observed row and column marginals across collections of subtables
(e.g. precincts, polling stations, or districts). References: Golan, A.,
