DOI: 10.1080/00949655.2024.2386391
Abstract: ABSTRACT The OLS and ridge regression (RR) estimators are adversely affected, when the problem of multicollinearity and y-direction outliers occur together. The robust ridge regression with penalized parameters offers biased estimators with lower variance than… read more here.

DOI: 10.1080/01490419.2019.1583147
Abstract: Abstract Although ridge tracing has the advantages of continuity and high positioning accuracy compared with other edge-based methods, it is difficult to use ridge tracing to extract coastlines from Synthetic Aperture Radar (SAR) images because… read more here.
