Response to Moffat's Comment on "Towards Meaningful Statements in IR Evaluation: Mapping Evaluation Measures to Interval Scales"
Marco Ferrante, Nicola Ferro, Norbert Fuhr
Moffat recently commented on our previous work. Our work focused on how laying the foundations of our evaluation methodology into the theory of measurement can improve our knowledg…
Towards Meaningful Statements in IR Evaluation. Mapping Evaluation Measures to Interval Scales
Marco Ferrante, Nicola Ferro, Norbert Fuhr
Recently, it was shown that most popular IR measures are not interval-scaled, implying that decades of experimental IR research used potentially improper methods, which may have pr…
A stochastic epidemic model of COVID-19 disease
Xavier Bardina, Marco Ferrante, Carles Rovira
To model the evolution of diseases with extended latency periods and the presence of asymptomatic patients like COVID-19, we define a simple discrete time stochastic SIR-type epide…
Strong approximations of Brownian sheet by uniform transport processes
Xavier Bardina, Marco Ferrante, Carles Rovira
Many years ago, Griego, Heath and Ruiz-Moncayo proved that it is possible to define realizations of a sequence of uniform transform processes that converges almost surely to the st…
Stochastic epidemic SEIRS models with a constant latency period
Xavier Bardina, Marco Ferrante, Carles Rovira
In this paper we consider the stability of a class of deterministic and stochastic SEIRS epidemic models with delay. Indeed, we assume that the transmission rate could be stochasti…
On the coupon-collector's problem with several parallel collections
Marco Ferrante, Alessia Tagliavini
In this note we evaluate the expectation and variance of the waiting time to complete parallel collections of coupons, in the case of coupons which arrives independently, one b…
