Choice of generalized linear mixed models using predictive crossvalidation

Braun, Julia; Sabanés Bové, Daniel; Held, Leonhard - In: Computational Statistics & Data Analysis 75 (2014) C, pp. 190-202

The choice of generalized linear mixed models is difficult, because it involves the selection of both fixed and random effects. Classical criteria like Akaike’s information criterion (AIC) are often not suitable for the latter task, and others which are useful in linear mixed models are...

Development of a control-oriented model to optimise fuel consumption and NOX emissions in a DI Diesel engine

Molina, S.; Guardiola, C.; Martín, J.; … - In: Applied Energy 119 (2014) C, pp. 405-416

This paper describes a predictive NOX and consumption model, which is oriented to control and optimisation of DI Diesel engines. The model applies the Response Surface Methodology following a two-step process: firstly, the relationship between engine inputs (intake charge conditions and...

Predictive ANN models of ground heat exchanger for the control of hybrid ground source heat pump systems

Gang, Wenjie; Wang, Jinbo - In: Applied Energy 112 (2013) C, pp. 1146-1153

Hybrid ground source heat pump (HGSHP) system coupled with supplemental heat rejection equipment in parallel configuration is suitable for buildings where the cooling load is much higher than the heating load. Appropriate control is expected to improve its energy efficiency. A control strategy...

Bayesian portfolio selection under a multifactor asset return model with predictive model selection

Ando, Tomohiro - In: Global Business and Economics Review 14 (2012) 1/2, pp. 77-101

This paper addresses the problem of portfolio selection under a multifactor asset return model, using Bayesian analysis to deal with uncertainties in parameter estimation and model specification. These sources of error are ignored in the classical mean-variance method. We apply two approaches:...

The Sense and Non-Sense of Holdout Sample Validation in the Presence of Endogeneity

Ebbes, Peter; Papies, Dominik; Heerde, Harald J. van - In: Marketing Science 30 (2011) 6, pp. 1115-1122

Market response models based on field-generated data need to address potential endogeneity in the regressors to obtain consistent parameter estimates. Another requirement is that market response models predict well in a holdout sample. With both requirements combined, it may seem reasonable to...
