Fast algorithm for smoothing parameter selection in multidimensional P-splines

Rodríguez-Álvarez, M.X.

; Lee, D.-J.

; Kneib, T.; Durban, M.; Eilers, P.H.C. (2015-12-31)

A new computational algorithm for estimating the smoothing parameters of a multidimensional penalized spline generalized model with anisotropic penalty is presented. This new proposal is based on the mixed model representation ...

Flexible geostatistical modeling and risk assessment analysis of lead concentration levels of residential soil in the Coeur D'Alene River Basin

Lee, D.-J.

; Toscas, P. (2015-12-31)

Soil heavy metals pollution is an urgent problem worldwide. Understanding the spatial distribution of pollutants is critical for environmental management and decision-making. Children and adults are still routinely exposed ...

Effect of various dietary regimens on oral challenge with Mycobacterium avium subsp. paratuberculosis in a rabbit model

Arrazuria, R.; Molina, E.; Mateo-Abad, M.; Arostegui, I.

; Garrido, J.M.; Juste, R.A.; Elguezabal, N. (2015-12-31)

Rabbits are susceptible to infection by Mycobacterium avium subspecies paratuberculosis (MAP) in both wildlife and experimental conditions. Under the hypotheses that nutrient balance might influence the establishment of ...

A decision tree to assess short-term mortality after an emergency department visit for an exacerbation of COPD: A cohort study

Esteban, C.; Arostegui, I.

; Garcia-Gutierrez, S.; Gonzalez, N.; Lafuente, I.; Bare, M.; Fernandez-de-Larrea, N.; Rivas, F.; Quintana, J.M. (2015-12-31)

Background: Creating an easy-to-use instrument to identify predictors of short-term (30/60-day) mortality after an exacerbation of chronic obstructive pulmonary disease (eCOPD) could help clinicians choose specific measures ...

Spatio-temporal functional data analysis for wireless sensor networks data

Lee, D.-J.

; Zhu, Z.; Toscas, P. (2015-05-05)

A new methodology is proposed for the analysis, modeling, and forecasting of data collected from a wireless sensor network. Our approach is considered in the framework of a functional data-analysis paradigm where observed ...

Penalized composite link mixed models for two-dimensional count data

Ayma, D.; Durban, M.; Lee, D.-J.

; Eilers, P.H.C. (2015-05)

Mortality data provide valuable information for the study of the spatial distribution of mortality risk, in disciplines such as spatial epidemiology, medical demography, and public health. However, they are often available ...
