1 Introduction

Measurement error (ME) is an integral part of any measurement proces where the values of about response of interest need to be determined [i]or[/i] part of to the other measurement. Thus, any investigation of the root-causes of a quality question or the implementation of Statistical Proces superintendence (SPC), involves measuring some variables, the actual values of which cannot be determined with absolute accuracy to be ascribed to ME. The study of ME in order to reveal sources that contribute to its variation, or the characterization of the distribution of ME between the sides of gage capability studies and via like measures as repeatability and reproducibility, are well established
