32 p, 463.2 KB Integer constraints for enhancing interpretability in linear regression / Carrizosa Priego, Emilio (Universidad de Sevilla. Departamento de Estadística e Investigación Operativa) ; Olivares-Nadal, Alba V. (The University of Chicago Booth School of Business) ; Ramírez-Cobo, Pepa (Universidad de Cádiz. Departamento de Estadística e Investigación Operativa)
One of the main challenges researchers face is to identify the most relevant features in a prediction model. As a consequence, many regularized methods seeking sparsity have flourished. Although sparse, their solutions may not be interpretable in the presence of spurious coefficients and correlated features. [...]

20 p, 317.5 KB Diagnostic plot for the identification of high leverage collinearity-influential observations / Bagheri, Arezoo (National Population Studies & Comprehensive Management Institute (Teheran, Iran)) ; Midi, Habshah (Universiti Putra Malaysia. Department of Mathematics)
High leverage collinearity influential observations are those high leverage points that change the multicollinearity pattern of a data. It is imperative to identify these points as they are responsible for misleading inferences on the fitting of a regression model. [...]
