cellKey: Consistent Perturbation of Statistical Frequency- And Magnitude
Tables
Data from statistical agencies and other institutions often
need to be protected before they can be published. This package
can be used to perturb statistical tables in a consistent way. The
main idea is to add - at the micro data level - a record key for each
unit. Based on these keys, for any cell in a statistical table a
cell key is computed as a function on the record keys contributing to
a specific cell. Values that are added to the cell in order to perturb
it are derived from a lookup-table that maps values of cell keys to
specific perturbation values. The theoretical basis for the methods
implemented can be found in Thompson, Broadfoot and Elazar
(2013) <https://unece.org/fileadmin/DAM/stats/documents/ece/ces/ge.46/2013/Topic_1_ABS.pdf>
which was extended and enhanced by Giessing and Tent
(2019) <https://unece.org/fileadmin/DAM/stats/documents/ece/ces/ge.46/2019/mtg1/SDC2019_S2_Germany_Giessing_Tent_AD.pdf>.
