    • On left-truncating and mixing poisson distributions 

      Valero Baya, Jordi; Pérez Casany, Marta; Ginebra Molins, Josep (2014-02-01)
      Article
      Open Access
      The distributions obtained by left-truncating at k a mixed Poisson distribution, kT-MP, and those obtained by mixing previously left-truncated Poisson distributions, M-kTP, are characterized by means of their probability ...
    • On poisson-stopped-sums that are mixed poisson 

      Valero Baya, Jordi; Pérez Casany, Marta; Ginebra Molins, Josep (2013)
      Article
      Restricted access - publisher's policy
      Maceda (1948) characterized the mixed Poisson distributions that are Poisson-stopped-sum distributions based on the mixing distribution. In an alternative characterization of the same set of distributions here the ...
    • Randomly stopped extreme Zipf extensions 

      Duarte López, Ariel; Pérez Casany, Marta; Valero Baya, Jordi (2021-03-23)
      Article
      Open Access
      In this paper, we extend the Zipf distribution by means of the Randomly Stopped Extreme mechanism; we establish the conditions under which the maximum and minimum families of distributions intersect in the original family; ...
    • The CHARME "Advanced Big Data Training School for Life Sciences": an example of good practices for training on current bioinformatics challenges 

      Hoang, Yen; Pfeil, Juliane; Zagoršcak, Maja; Zdravevski, Eftim; Ramšak, Živa; Schulze, Sabrina K.; Papageorgiou, K.; Duarte López, Ariel; Pérez Casany, Marta (2019-02-05)

    • The Zipf-Polylog distribution: Modeling human interactions through social networks 

      Valero Baya, Jordi; Pérez Casany, Marta; Duarte López, Ariel (2022-10)
      Article
      Open Access
      The Zipf distribution attracts considerable attention because it helps describe data from natural as well as man-made systems. Nevertheless, in most of the cases the Zipf is only appropriate to fit data in the upper tail. ...
    • The Zipf–Poisson-stopped-sum distribution with an application for modeling the degree sequence of social networks 

      Duarte López, Ariel; Pérez Casany, Marta; Valero Baya, Jordi (2020-03-01)
      Article
      Open Access
      Under the Zipf Distribution, the frequency of a value is a power function of its size. Thus, when plotting frequencies versus size in log–log scale of data following that distribution, one obtains a straight line. The Zipf ...

      Article
      Open Access
      1. Zeros (i.e. events that do not happen) are the source of two common phenomena in count data: overdispersion and zero-inflation. Zeros have multiple origins in a dataset: false zeros occur due to errors in the experimental ...
