A new evidence measure for Bayesian Inference
In the last sixty years there have been several attempts to build a measure of evidence that covers, in a Bayesian context, the role that the p-value has played in the frequentist setting. A prominent example is the decision test based on the Bayes Factor. Worth to mention it is also the e-value, …

Mediation analysis for different types of Causal questions: Effect of Cause and Cause of Effect
Many statistical analyses aim at a causal explanation of the data. When discussing this topic it is important to specify the exact query we want to talk about. A typical causal question can be categorized in two main classes: questions on the causes of observed effects and questions on the effects …

Objective bayesian variable selection for censored data
In this thesis we study the problem of selecting a set of regressors when the response variable follows a parametric model (such as Weibull or lognormal) and observations are right censored. Under a Bayesian approach, the most widely used tools are the Bayes Factors (BFs) which are, however, …

FUNCTIONAL STATISTICAL LEARNING METHODS APPLIED TO HUMAN EMOTION RECOGNITION FROM FACIAL VIDEOS
… corresponding emotions. By harnessing functional statistical learning methods, we develop a comprehensive methodology that capitalizes on the dynamic properties of continuity and evolvability inherent in functional data extracted from facial videos, which possess distinct properties compared to …

GAUSSIAN PROCESSES FOR 3D SHAPE MODELLING OF NOISY AND INCOMPLETE DATA. AN APPLICATION TO HUMAN EARS RECONSTRUCTION
Mathematical modelling of 3D shapes is a requirement in a vast and increasing number of applications, especially when it comes to the human shape. Despite being an active branch of research, with many proposed solutions, some settings remain particularly challenging. An example of such an open …

Parametric modeling of dependence of bivariate quantile regression residuals' signs
In this thesis, we propose a non-parametric method to study the dependence of the quantiles of a multivariate response conditional on a set of covariates. We define a statistic that measures the conditional probability of concordance of the signs of the residuals of the conditional quantiles of …
