%description
Turns de-identified tables ('Excel' workbooks or delimited text files)
into synthetic counterparts with the same layout, the same identifiers and
the same data-entry quirks. Every non-identifier cell, missingness
included, is censored once per sweep and redrawn by copying the raw value
of a donor drawn from a classification and regression tree leaf fitted on
the rest of the table, in the spirit of the sequential tree-based
synthesis of Reiter (2005) "Using CART to generate partially synthetic
public use microdata", Journal of Official Statistics 21(3):441-462, and
Nowok, Raab and Dibben (2016) <doi:10.18637/jss.v074.i11>. Identifiers are
kept so that tables stay joinable, and columns of other tables can
condition the synthesis so cross-table associations survive a later join.
Synthetic copies are intended for developing and testing analysis code;
they are not an anonymisation method.
