Statistical Models for Corporate Credit Risk Assessment – Rating Models

Acta Universitatis Lodziensis. Folia Oeconomica, 2016
Taking into consideration the weakness of the models based on discrimination function (Z-score) proposed by Altman within the conditions of polish economy some attempts were taken in the 90s to adjust these models to the reality of post-communist economy.

Parsimonious statistical learning models for low-flow estimation [PDF]

Hydrology and Earth System Sciences, 2022
Statistical learning methods offer a promising approach for low-flow regionalization. We examine seven statistical learning models (Lasso, linear, and nonlinear-model-based boosting, sparse partial least squares, principal component regression, random ...
