%description
Provides a revised framework for statistical matching of categorical data
based on latent class models, including multiple imputation, predictive
modeling, nearest-neighbour hot-deck matching, and probabilistic
assignment of categorical target variables. It allows researchers to
perform data integration when no unique identifiers are available by
modeling the joint distribution of variables through latent categorical
structures. The package supports estimation of latent class models,
probabilistic matching between donor and recipient data sets, and
generation of synthetic linked data under uncertainty. It is particularly
useful in survey research and data fusion applications where combining
information from multiple sources is required while preserving statistical
properties and accounting for measurement error and missing data
mechanisms. The latent class matching methods are described by Lewaa,
Hafez and Ismail (2023) <doi:10.18576/jsap/120123>. (2.0->2.1): in
smc2_step2() Gower distance is replaced by Euclidean distance in hot deck
method.
