On statistical model extensions based on randomly stopped extremes Open
The maxima and the minima of a randomly stopped sample of a random variable, $X$, together with two newly defined random variables that make $X$ into the maxima or minima of a randomly stopped sample of them, can be used to define statisti…

Conditional Poisson Regression with Random Effects for the Analysis of Multi-site Time Series Studies Open
The analysis of time series studies linking daily counts of a health indicator with environmental variables (e.g., mortality or hospital admissions with air pollution concentrations or temperature; or motor vehicle crashes with temperature…

Mapping Life Expectancy Loss in Barcelona in 2020 Open
We use a Bayesian spatio-temporal model, first to smooth small-area initial life expectancy estimates in Barcelona for 2020, and second to predict what small-area life expectancy would have been in 2020 in absence of covid-19 using mortali…

Alcohol as a trigger of migraine attacks in people with migraine. Results from a large prospective cohort study in English‐speaking countries Open
Objective To assess whether alcohol intake is associated with the onset of migraine attacks up to 2 days after consumption in individuals with episodic migraine (EM). Background Although alcohol has long been suspected to be a common migra…

Bayesian Spatiotemporal Model for Life Expectancy Mapping; Changes in Barcelona From 2007 to 2018 Open
When mapping life expectancy, and investigating its local variation in time, there is a conflict between using large areas and/or mortality data from long periods of time to have low variance life expectancy estimates, and using small area…

Mapping vote transition at the 2012 outset of the Catalan push for independence Open
In 2012 Catalan politics came to a standstill, and a push for independence was triggered by a huge pro-independence rally. That push led, in 2017, to the Spanish government taking over the Catalan government, and top Catalan officials eith…

Outlier detection for multivariate categorical data Open
The detection of outlying rows in a contingency table is tackled from a Bayesian perspective, by adapting the framework adopted by Box and Tiao for normal models to multinomial models with random effects. The solution assumes a 2–component…

pyGPGO: Bayesian Optimization for Python Open
Bayesian optimization has risen over the last few years as a very attractive method to optimize expensive to evaluate, black box, derivative-free and possibly noisy functions (Shahriari et al. 2016).This framework uses surrogate models, su…

Bayesian Analysis of the Heterogeneity of Literary Style Open
We proposed statistical analysis of the heterogeneity of literary style in a set of texts that simultaneously use different stylometric characteristics, like word length and the frequency of function words. The data set consists of several…

A Unified Approach to Authorship Attribution and Verification Open
In authorship attribution, one assigns texts from an unknown author to either one of two or more candidate authors by comparing the disputed texts with texts known to have been written by the candidate authors. In authorship verification, …
