24 p, 3.9 MB Bayesian joint spatio-temporal analysis of multiple diseases / Gómez-Rubio, Virgilio (Universidad de Castilla-La Mancha) ; Palmí-Perales, Francisco (Universidad de Castilla-La Mancha) ; López-Abente, Gonzalo (Instituto de Salud Carlos III) ; Ramis-Prieto, Rebeca (Instituto de Salud Carlos III) ; Fernández-Navarro, Pablo (Instituto de Salud Carlos III)
In this paper we propose a Bayesian hierarchical spatio-temporal model for the joint analysis of multiple diseases which includes specific and shared spatial and temporal effects. Dependence on shared terms is controlled by disease-specific weights so that their posterior distribution can be used to identify diseases with similar spatial and temporal patterns. [...]

15 p, 509.9 KB Neural nets for indirect inference / Creel, Michael (Universitat Autònoma de Barcelona. Departament d'Economia i d'Història Econòmica)
This paper shows how neural networks may be used to approximate the limited information posterior mean of a simulable model. Because the model is simulable, training and testing samples may be generated with sizes large enough to train well a net that is large enough, in terms of number of hidden layers and neurons, to learn the limited information posterior mean with good accuracy.

Les ones gravitatòries són una predicció de la teoria de la Relativitat General d'Einstein, la detecció i anàlisi de les quals obrirà una nova àrea en el nostre coneixement de l'Univers. En efecte, aquestes ones porten informació de sistemes amb gravetat molt forta i que són molt difícils d'observar amb instruments convencionals, basats en la detecció de llum, per a qual cosa el nostre coneixement actual només en pot ser parcial. [...]
Gravitational waves are a prediction of Einstein's General Relativity, the detection and analysis of which will open a new area in our understanding of the Universe. Indeed, these waves carry information from systems with strong gravity and are very difficult to observe with conventional instruments, which are based on the detection of light. [...]

Department of Economics) ; Guillén, Montserrat (Universitat de Barcelona. Departament d'Econometria) ; Xarxa de Referència en Economia Aplicada (XREAP)
We present a real data set of claims amounts where costs related to damage are recorded separately from those related to medical expenses. Only claims with positive costs are considered here. Two approaches to density estimation are presented: a classical parametric and a semi-parametric method, based on transformation kernel density estimation. [...]
