The measurements results adjustment by the Least Square Method

The method for processing of the measurement results obtained from Comite International des Poids et Measures (CIPM) Key, Regional Metrology Organizations (RMO) or supplementary comparisons, proficiency testing by interlaboratory comparisons and calibrations is proposed. It named authors as adjustment least square (LSM). Additive multiplicative parameters each measuring standard every particular laboratory will be this adjustment. As well artifact.
 measurements standards are their additive degrees equivalence comparison estimations systematic errors (biases) calibrations. artifacts key reference value assigned quantity values calibrations.
 considered a way to solving problem great amount homogeneous with many at different levels (CIPM, RMO supplementary), including connected problems.
 Four cases adjustments considered. first one free case was so because fact that none participants has any advantage except uncertainties measurements.
 second fixed Measuring rigidly linked laboratories participated in CIPM comparisons.
 third dependent equations. This not new previous some other case. means influenced known vice versa.
 fourth additional summary In certain checking equations added system So, sum multiplied weights all should equal zero.
