Abstract : This work presents a technique that can completely and accurately identify measurement bias in cases where it is not possibleto use the method of Rollins and Davis (1992, 1993) and where the method of Narasimhan and Mah (1987) fail to performaccurately. This technique makes use of information contained in the relationship between individual measurements and thecorresponding nodal imbalance. The performance of this method is demonstrated on a problem from the literature that has beendifficult for other methods to handle. In addition, this article discusses how the new technique can be used as a visual monitoringtool for identifying biased measured variables.
