Suda 2 is a recursive algorithm for finding Minimal Sample Uniques. The algorithm generates all possible variable subsets of defined categorical key variables and scans them for unique patterns in the subsets of variables. The lower the amount of variables needed to receive uniqueness, the higher the risk of the corresponding observation.
A modified sdcMicroObj object or the following list
ContributionPercent
: The contribution of each key variable to the SUDA
score, calculated for each row.
score
: The suda score
'disscore: The dis suda score
attribute_contributions:
a data.frame
showing how much of the total
risk is contributed by each variable. This information is stored in the
following two variables:
variable
: containing the name of the variable
contribution
: contains how much risk a variable contributes to the total risk.
attribute_level_contributions
: returns risks of each attribute-level as a
data.frame
with the following three columns:
variable
: the variable name
attribute
: holding relevant level-codes
contribution
: contains the risk of this level within the variable.
Since version >5.0.2, the computation of suda-scores has changed and is now by default as described in the original paper by Elliot et al.
