Analysing Error of Fit Functions for Ellipses
We describe several established error of fit (EOF) functions for use in the least square fitting of ellipses, and introduce a further four new EOFs. Four measures are given for assessing the suitability of such EOFs, quantifying their linearity, curvature bias, asymmetry, and overall goodness. These measures enable a better understanding to be gained of the individual merits of the EOF functions.
متن کاملNOTE: Assessing Error of Fit Functions for Ellipses
j51 ej . A variety of error of fit (EOF) functions have been proposed for use in the least-square fitting of ellipses. We describe four measures for assessing the suitability of such EOFs, quantifying Thus, many different ellipse estimation techniques detheir linearity, curvature bias, asymmetry, and overall goodpend on a suitable error term, although there has been ness. These measures enable ...
متن کاملCombining Error Ellipses
The purpose of this document is to present a formalism for statistically averaging source positions and their uncertainties for use in the level-3 pipeline. More specifically, the problem addressed here is to find an improved estimate for the position of a source from previous independent estimates of its position. The uncertainties of the estimates are expressed in the form of error ellipses c...
متن کاملGoodness-of-Fit Test for Monotone Functions
In this article, we develop a test for the null hypothesis that a real-valued function belongs to a given parametric set against the non-parametric alternative that it is monotone, say decreasing. The method is described in a general model that covers the monotone density model, the monotone regression and the right-censoring model with monotone hazard rate. The criterion for testing is an L p-...
متن کاملAnalysing Safety Functions and Barriers
The paper gives a summary of approaches to describing and modelling safety characteristics, including safety functions and barriers. In three examples, the safety function concept has been used to describe how actual safety systems worked. The examples are an incident investigation, a safety analysis of a part of a pharmaceutical plant, and safety rules in the railway industry. Advantages and d...
