If systematic accuracy **bias is ignored,** the Grubbs-Liu estimator is equivalent to the Grubbs-Pearson estimator. Having an accuracy of 5m (95%) means that in 95% of the time the positioning error will be equal or below 5m. This distribution is described in the Closed Form Precision section.

Conversion between CEP, RMS, 2DRMS, and R95[edit] While 50% is a very common definition for CEP, the circle dimension can be defined for percentages. Circular Error Pendulum Systematic Accuracy Bias Some approaches to estimating CEP conflate the question of precision with the question of accuracy, or "sighting in." The simpler case only tries to estimate precision, and computes

Further complications arise because some navigation systems are linear (one-dimensional) while others provide two or three dimensions of position[1].

The Grubbs-Pearson estimator (Grubbs, 1964) shares its assumptions with the general correlated normal estimator. http://webmail.igage.com/mp/GPSAccuracy.htm ISBN978-0-262-13258-9. Circular Error Probable Excel This question has been studied, e.g., by Williams (1997). Circular Error Probable Matlab Munitions may also have larger standard deviation of range errors than the standard deviation of azimuth (deflection) errors, resulting in an elliptical confidence region.
