ptable-class

An S4 class to represent perturbation table

Tabular data from statistical institutes and agencies are mostly
confidential and must be protected prior to publications. The cell-key
method is a post-tabular Statistical Disclosure Control perturbation
technique that adds random noise to tabular data. The statistical
properties of the perturbations are defined by some noise probability
distributions - also referred to as perturbation tables.
This tool can be used to create the perturbation tables based on a maximum
entropy approach as described for example in Giessing (2016)
<doi:10.1007/978-3-319-45381-1_18>. The perturbation tables created can
finally be used to apply a cell-key method to frequency count or magnitude
tables.
