Modeling structural change in the European metropolitan areas during the process of economic integration

Longhi, Christian; Musolesi, Antonio; Beaumont, Catherine - Département Sciences Sociales, Agriculture et … - 2014

The specialization patterns of metropolitan areas are crucial in characterizing the effects of economic integration in Europe. This paper aims to provide and estimate an econometric model that explains both sectoral specialization and sectoral dissimilarity, measured with the GINI and the...

On concurvity in nonlinear and nonparametric regression models

Amodio, Sonia; Aria, Massimo Aria; Antonio D’Ambrosio - In: Statistica 74 (2014) 1, pp. 81-94

When data are affected by multicollinearity in the linear regression framework, then concurvity will be present in fitting a generalized additive model (GAM). The term concurvity describes nonlinear dependencies among the predictor variables. As collinearity results in inflated variance of the...

Monotone splines lasso

Bergersen, Linn Cecilie; Tharmaratnam, Kukatharmini; … - In: Computational Statistics & Data Analysis 77 (2014) C, pp. 336-351

The important problems of variable selection and estimation in nonparametric additive regression models for high-dimensional data are addressed. Several methods have been proposed to model nonlinear relationships when the number of covariates exceeds the number of observations by using spline...

Modeling CRS bounded additive DEA models and characterizing their Pareto-efficient points

Pastor, Jesus; Aparicio, Juan; Monge, Juan; Pastor, Diego - In: Journal of Productivity Analysis 40 (2013) 3, pp. 285-292

Dealing with weighted additive models in Data Envelopment Analysis guarantees that any projection of an inefficient … additive models require a double set of slacks. The second set of slacks allows us to properly characterize all the Pareto …-efficient points associated to the bounded technology. We further introduce the CRS partially-bounded additive models.
