Modified Galton-Watson processes with immigration under an alternative offspring mechanism

Wagner Barreto-Souza, Sokol Ndreca, Rodrigo B. Silva +1

We propose a novel class of count time series models alternative to the classic Galton-Watson process with immigration (GWI) and Bernoulli offspring. A new offspring mechanism is d…

Percolation of words on the hypercubic lattice with one-dimensional long-range interactions

Pablo A. Gomes, Otávio Lima, Roger W C Silva

We investigate the problem of percolation of words in a random environment. To each vertex, we independently assign a letter or according to Bernoulli r.v.'s with parameter…

Exponential decay for Constrained-degree percolation

Diogo C. dos Santos, Roger W. C. Silva

We consider the Constrained-degree percolation model in random environment (CDPRE) on the square lattice. In this model, each vertex has an independent random constraint …

Fractional Poisson random sum and its associated normal variance mixture

Gabriela Oliveira, Wagner Barreto-Souza, Roger W. C. Silva

In this work, we study the partial sums of independent and identically distributed random variables with the number of terms following a fractional Poisson (FP) distribution. The F…

Constrained-degree percolation in random environment

Rémy Sanchis, Diogo C. dos Santos, Roger W. C. Silva

We consider the Constrained-degree percolation model in random environment on the square lattice. In this model, each vertex has an independent random constraint which ta…

Exact and computationally efficient Bayesian inference for generalized Markov modulated Poisson processes

Flavio B. Gonçalves, Livia M. Dutra, Roger W. C. Silva

Statistical modeling of point patterns is an important and common problem in several areas. The Poisson process is the most common process used for this purpose, in particular, its…

Convergence and inference for mixed Poisson random sums

Wagner Barreto-Souza, Gabriela Oliveira, Roger W. C. Silva

In this paper we obtain the limit distribution for partial sums with a random number of terms following a class of mixed Poisson distributions. The resulting weak limit is a mixing…

Multivariate Log-Skewed Distributions with normal kernel and their Applications

Marina M. de Queiroz, Rosangela H. Loschi, Roger W. C. Silva

We introduce two classes of multivariate log skewed distributions with normal kernel: the log canonical fundamental skew-normal (log-CFUSN) and the log unified skew-normal (log-SUN…

On a Local Version of the Bak-Sneppen Model

Iddo Ben-Ari, Roger W. C. Silva

A major difficulty in studying the Bak-Sneppen model is in effectively comparing it with well-understood models. This stems from the use of two geometries: complete graph geometry…

Marina Muniz, Roger Silva, Rosangela Loschi

This paper mainly focuses on studying the Shannon Entropy and Kullback-Leibler divergence of the multivariate log canonical fundamental skew-normal (LCFUSN) and canonical fundament…
