M-Estimation as a Tool Supporting a Vessel Traffic Controller in the VTS System
Polish Maritime Research, 2015 In order to improve maritime safety and the efficiency of vessel traffic, systems supervising vessel traffic, i.e. VTS (Vessel Traffic Service), started to be created.

On Inconsistent $M$-Estimators
The Annals of Statistics, 1982 If $M$ is not convex, and the underlying density is multi-modal, $M$-estimators can be inconsistent. Examples are given, as well as some positive results.

Generalized Projection-Based M-Estimator [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2012 We propose a novel robust estimation algorithm—the generalized projection-based M-estimator (gpbM), which does not require the user to specify any scale parameters. The algorithm is general and can handle heteroscedastic data with multiple linear constraints for single and multicarrier problems.

Barekeng, 2022 The study aimed to compare a few robust approaches in linear regression in the presence of outlier and high leverage points. Ordinary least square (OLS) estimation of parameters is the most basic approach practiced widely in regression analysis. However,

Biometrika, 2023 Summary We characterize the full classes of M-estimators for semiparametric models of general functionals by formally connecting the theory of consistent loss functions from forecast evaluation with the theory of M-estimation. This novel characterization result allows us to leverage existing results on loss functions known from the ...

Determination of Terrain Profile from TLS Data by Applying Msplit Estimation
Remote Sensing, 2020 This paper presents an application of an Msplit estimation in the determination of terrain profiles from terrestrial laser scanning (TLS) data. We consider the squared Msplit estimation as well as the absolute Msplit estimation.
