aggrtab

internal

A statistical disclosure control tool to protect frequency tables in cases where small values are sensitive. The function PLSrounding() performs small count rounding of necessary inner cells so that all small frequencies of cross-classifications to be published (publishable cells) are rounded. This is equivalent to changing micro data since frequencies of unique combinations are changed. Thus, additivity and consistency are guaranteed. The methodology is described in Langsrud and Heldal (2018) <https://www.researchgate.net/publication/327768398_An_Algorithm_for_Small_Count_Rounding_of_Tabular_Data>.

aggrtab function

<dl><dt>A</dt>
<dd>A data frame representing a micro dataset or a frequency count hypercube. The (first) columns
define the variables. If A is a hypercube the last column contains the number of units in each cell.</dd>
<dt>d</dt>
<dd>A list d{[[j]]} whose elements are vectors of variable names from A defining marginal tables/cubes 
of A that we are interested in.</dd>
<dt>micro</dt>
<dd>Logical. TRUE if A is a micro dataset (default). FALSE if A i a frequency count hypercube.</dd>
<dt>nin</dt>
<dd>Name of count variable if A is a hypercube. Default name: "n".</dd>
<dt>nout</dt>
<dd>Name of the frequency count variable in the output tables.</dd></dl>
