Discriminant Analysis Using Least Absolute Deviations [PDF]
Decision Sciences, 1990 ABSTRACTSeveral linear programming methods have been suggested as discrimination procedures. A least absolute deviations regression procedure is developed here which is simpler to use and does not suffer from any lack of invariance. A simulation study shows it to be at least as effective as any of the methods previously discussed for normal and heavy ...

Consensual Regression of Lasso-Sparse PLS models for Near-Infrared Spectra of Food
Agriculture, 2022 In some cases, near-infrared spectra (NIRS) make the prediction of quantitative models unreliable, and the choice of a suitable number of latent variables (LVs) for partial least square (PLS) is difficult. In this case, a strategy of fusing member models

Two variants of M split estimation – similarities and differences [PDF]
Advances in Geodesy and Geoinformation, 2022 M split estimation is a novel method developed to process observation sets that include two (or more) observation aggregations. The main objective of the method is to estimate the location parameters of each aggregation without any preliminary assumption

Robust Statistical Detection of GNSS Multipath Using Inter-Frequency C/N0 Differences
Remote Sensing, 2020 Multipath detection and mitigation are crucial issues for global navigation satellite system (GNSS) high-precision positioning. The multi-frequency carrier power-to-noise density ratio (C/N0)-based multipath detection technique has achieved good results ...

The Retrieval Phase of the Hopfield Model: A Rigorous Analysis of the Overlap Distribution [PDF]
, 1995 Standard large deviation estimates or the use of the Hubbard-Stratonovich transformation reduce the analysis of the distribution of the overlap parameters essentially to that of an explicitly known random function $\Phi_{N,\b}$ on $\R^M$. In this article
