Description of accuracy using conventional and robust estimates of scale

Abstract

At first, the term “accuracy measure”; is described for the one‐dimensional case. Then, the limitations under which conventional methodology of accuracy expressions is useful and the effects of various degrees of assumption failures are examined. Next the criteria of appropriateness, completeness, resistance, and efficiency are set forth as the generic requirements of an investigation into properly selecting scale estimators. Finally, reliable and efficient accuracy measures are proposed for expressing one‐dimensional position uncertainty.
