Location Estimators and Spread

Multivariate Monotone Location Estimators

A notion of monotonicity of multivariate location estimators is introduced. The relationships between this notion and other existing notions are discussed. Finite sample breakdown point properties of multivariate monotone location estimators are investigated. It turns out that the breakdown points of typical multivariate monotone location estimators are independent of the configuration of under...

Location Estimators for Interferometric Fringes

Future global astrometry missions have targeted the determination of positions, parallaxes, and annual proper motions to the 10 mas level. This can be achieved through the use of fringe imaging interferometers, possibly featuring wide fields of view (e.g., Fizeau configurations). The basic location information is to be extracted from the fringe pattern by proper implementation of the detection ...

Comparison of Optimal Location Estimators

Improved Spread-Location Visualization

Cleveland (1979, 1993) introduced the spread-location plot as a diagnostic plot suitable for many types of fitted statistical models. The spread-location plot which plots the absolute residual or square-root absolute residual vs. fitted value along with a robust loess smooth is a useful replacement for the customary practice of plotting residuals vs. fitted values. In this note, we show that ne...
