Estimating the tail index of Pareto-type distributions from geometric records

Martín Alcalde, Raúl Gouet, Miguel Lafuente +2

In this paper, we develop a novel inferential approach based on geometric records for estimating the tail index of heavy-tailed distributions. We construct a maximum likelihood est…

Decision-Aware Proximal Bridge Learning for Optimal Treatment Selection

Tomàs Garriga, Alejandro Almodóvar, Axel Brando +3

Individualized treatment selection with continuous actions requires accurate causal response estimation in decision-relevant regions, rather than uniformly over the entire action s…

Characterisation of distributions via record-like observations

Raúl Gouet, Miguel Lafuente, F. Javier López +1

We characterise probability distributions via a martingale property associated with a natural generalisation of record values, known as -records. For an independent and identic…

Stochastic ordering, attractiveness and couplings in non-conservative particle systems

Raúl Gouet, F. Javier López, Gerardo Sanz

We analyse the stochastic comparison of interacting particle systems allowing for multiple arrivals, departures and non-conservative jumps of individuals between sites. That is, if…

Estimating hazard rates from -records in discrete distributions

Martín Alcalde, Miguel Lafuente, F. Javier López +2

This paper focuses on nonparametric statistical inference of the hazard rate function of discrete distributions based on -record data. We derive the explicit expression of the…
