ABSTRACT
From Section 12.3.1 recall an important fact - obtaining an estimate is not necessarily the only end goal of an estimation exercise. An equally important goal is to quantify the errors incurred in estimation and provide a confidence region for the “truth.” We have previously discussed the sources of estimation errors in Chapter 12. A realistic experimental design can at best only minimize some sources of errors, but not eliminating them. Zero error occurs only in an idealistic setting, since even the most careful experiment is not impervious to factors beyond our control.
