Perturbed Estimates
Summary  Adjusts the sum of a measure so that the ratio of perturbed sum and perturbed mean is equal to the perturbed contributor count. 

Notes  This module adjusts the sum of a measure to make it consistent with the perturbed count by multiplying the unperturbed mean of the measure by the perturbed contributor count:
CODE
This has the effect of proportionately scaling the sum to be consistent with the change that perturbation has applied to the count. The "contributor count" used in the calculation is the count of nonnull values for that measure. This will be less than the record count if the data has null values. You should therefore take care to ensure that any genuine null values in the data are channelled to the SXV4 as null, rather than as 0. This module is not required if you are only using discrete perturbation and do not have any measures available.

Dependencies  Perturbation 
Priority  Perturbed estimates uses the results of discrete perturbation in its calculation, so it must always run after the perturbation module. If you are using weighted datasets and/or continuous perturbation, then the modules must run in the following sequence:
