FHLocalizer-class: Feligi-Holt Errorlocalizer

FHLocalizer-classR Documentation

Feligi-Holt Errorlocalizer

Description

Implementation of the Feligi-Holt algorithm using the ErrorLocalizer base class. Given a set of validation rules and a dataset the Feligi-Holt algorithm finds for each record the smallest (weighted) combination of variables that are erroneous (if any).

Note

Most users do not need this class and can use locate_errors().

errorlocalizer implements feligi holt using a MIP-solver. For problems in which coefficients of the validation rules or the data are too different, you should consider scaling the data.
