SmallCountRounding 1.0.0

• New function, PLSroundingLoop: PLSrounding on portions of data at a time.
  • The runs are coordinated by using preliminary differences as input for the next run (parameter preDifference)
• Parameters zeroCandidates, forceInner, preRounded and plsWeights can now be specified as functions.
  • These cannot be supplied as vectors in PLSroundingLoop.
• New parameter, allSmall.
  • When TRUE, all small inner cells (<= maxRound) are rounded. A simplified alternative to specifying forceInner.
• Adaption needed after Matrix ver. 1.4-2 (not a user-visible change)

SmallCountRounding 0.9.0

• New function, PLSroundingFits, for post-processing to expected frequencies
  • Expected inner cell frequencies are generated by iterative proportional fitting
• plsWeights is new parameter to RoundViaDummy (and PLSrounding)
  • A vector of weights for each cell to be published or a function generating it. For use in the algorithm criterion.

SmallCountRounding 0.8.0

• Now, microdata input is allowed. This is due to
  • Allowing empty freqVar in input.
  • The new parameter preAggregate: When TRUE, the data will be aggregated beforehand within the function by the dimensional variables.
• It is possible to avoid handling hierarchical variables when using the formula interface.
  • This is a consequence of parameter avoidHierarchical to Formula2ModelMatrix in the SSBtools package.

SmallCountRounding 0.7.0

• Now, a random generator seed is used locally within the function without affecting the random value stream in R.
  • Handled by rndSeed, a new parameter to RoundViaDummy (and PLSrounding).
  • By default, rndSeed = 123. This means that repeated runs with equal input will result in equal output.
  • To get back the old behaviour of the function, set rndSeed to NULL.
• Possible to return a single data frame: "inner" or "publish".
  • Handled by output, a new parameter to PLSrounding.
  • New wrapper functions, PLSroundingInner and PLSroundingPublish.
• dimVar is new parameter to RoundViaDummy and PLSrounding
  • The main dimensional variables and additional aggregating variables. This parameter can be useful when hierarchies and formula are unspecified.

SmallCountRounding 0.6.0

• preRounded is new parameter to RoundViaDummy (and PLSrounding)
  • A mixture of missing values and predetermined values of rounded inner cells

SmallCountRounding 0.5.0

• Formula combined with hierarchies is now possible
  • This is a consequence of the function HierarchiesAndFormula2ModelMatrix in the SSBtools package
• leverageCheck and easyCheck are new parameters to RoundViaDummy
  • This provides protection against possible disclosure of small numbers by linear relationships (difference attack)
  • The function Reduce0exact in the SSBtools package is utilised
• printInc is new parameter to PLSrounding and RoundViaDummy
  • Whether to print iteration information to the console
• Possible to specify removeEmpty=TRUE to omit empty combinations
  • Parameter to Hierarchies2ModelMatrix and HierarchiesAndFormula2ModelMatrix in the SSBtools package
• The parameter inputInOutput is also mentioned in the RoundViaDummy documentation
  • Parameter to same functions as above
  • Can be used to specify whether to include codes from input
• A vignette, “Introduction to ‘SmallCountRounding’”, is included
