System and method for statistical measurment validation

An apparatus, comprising:

• an input interface;
• a communication interface;
• a memory;
• and
• a controller adapted to:
• obtain a measured value via the input interface;
• determine a histogram bin into which the measured value falls;
• and
• report via the communication interface as a measurement result a confidence interval stored in the memory, the confidence interval associated with the histogram bin, wherein the associated confidence interval is calculated from a subset of training values, the subset of training values falling within the histogram bin.

A system, comprising:

• a sub-system having an operational characteristic;
• and
• a measurement system adapted to measure the operational characteristic, the measurement system comprising:
• an input interface coupled to the sub-system;
• a communication interface;
• a memory;
• and
• a measurement controller adapted to:
• obtain a measured value of the operational characteristic via the input interface;
• determine a histogram bin into which the measured value falls;
• and
• report via the communication interface as a measurement result a confidence interval stored in the memory, the confidence interval associated with the histogram bin, wherein the associated confidence interval is calculated from a subset of training values, the subset of training values falling within the histogram bin.
