Claim 11:
12. A system, comprising:
at least one computer, comprising:
at least one processor and
a non-transient storage subsystem;
wherein the non-transient storage subsystem stores a computer program comprising instructions that, when executed by the at least one processor, cause the at least one processor to at least:
electronically receive at least the following:
a model for one or more operating conditions and
facility operating data of the one or more operating conditions for each respective facility of a plurality of facilities;
wherein the model comprises one or more coefficients;

determine one or more acceptable bias criteria associated with the model;
iteratively perform one or more iterations of outlier bias reduction in the facility operating data of the plurality of facilities based at least in part on the model;
wherein the iterative performance of the one or more iterations of outlier bias reduction comprises computer operations of:
 (i) determining a set of model-predicted values;
 (ii) comparing the set of model-predicted values to the facility operating data to produce a set of error values;
 (iii) removing bias facility operating data of one or more performance outlier facilities from the facility operating data of the plurality of facilities to form a non-biased facility operating data of one or more performance non-biased facilities that are selected from the plurality of facilities, wherein the one or more performance outlier facilities are determined based at least in part on the set of error values and the one or more acceptable bias criteria;
 (iv) constructing, based at least in part on the non-biased facility operating a data, an updated model for the one or more operating conditions, wherein the updated model comprises one or more updated coefficients;
 (v) repeating steps (i) through (iv) when one or more termination criteria are not satisfied;

determine, based at least in part on the non-biased facility operating data for the one or more operating conditions of the one or more performance non-biased facilities, one or more non-biased performance standards for the one or more operating conditions; and
track, based at least in part on the one or more non-biased performance standards and the facility operating data, operating performance of each respective facility of the plurality of facilities so that operating performance comports with the one or more non-biased performance standards.
