Claim One:
1. A system for reducing outlier bias in target variables measured for a facility comprising: a computing unit for processing a data set, the computing unit comprising a processor and a storage subsystem; an input unit for inputting the data set to be processed, the input unit comprising a measuring device for measuring a target variable for the facility and for providing a corresponding data set; an output unit for outputting a processed data set; a computer program stored by the storage subsystem comprising instructions that, when executed, cause the processor to execute following steps: selecting a target variable for the facility; selecting a set of actual values of the target variable; identifying a plurality of variables for the facility that are related to the target variable; obtaining a data set for the facility, the data set comprising values for the plurality of variables; selecting a bias criteria; selecting a set of model coefficients; (1) generate a set of predicted values for the data set; (2) generate an error set for the data set; (3) generate a set of error threshold values based on the error set and the bias criteria; (4) generate a censored data set based on the error set and the set of error threshold values; (5) generate a set of new model coefficients; and (6) using the set of new model coefficients, repeat steps (1)-(5), unless a censoring performance termination criteria is satisfied.
