The Index Distribution of Gaussian Random Matrices
, 2009 We compute analytically, for large N, the probability distribution of the number of positive eigenvalues (the index N_{+}) of a random NxN matrix belonging to Gaussian orthogonal (\beta=1), unitary (\beta=2) or symplectic (\beta=4) ensembles.

Semiparametric Additive Beta Regression Models
Revstat Statistical Journal, 2021 In this paper, we study a semiparametric additive beta regression model using a parameterization based on the mean and a dispersion parameter. This model is useful for situations where the response variable is continuous and restricted to the unit ...

Exponentiated beta distributions
Computers & Mathematics with Applications, 2005 AbstractBeta distributions are usually defined on the unit interval [0,1]. For wider applicability, we introduce six exponentiated beta distributions and derive several of their properties, including the moment generating function, expectation, variance, skewness, kurtosis, Shannon entropy, and the Rényi entropy.

Stochastic domination in beta ensembles [PDF]
arXiv, 2023 We give a stochastic comparison and ordering of the largest eigenvalues, with parameter $\beta$, for Hermite $\beta$-ensembles and Laguerre $\beta$-ensembles. Although stochastic comparison results are well known in Laguerre ensembles (for $\beta=1,2,4$) using the last passage percolation models, our results are novel even for $\beta=1,2,4$, in Hermite

Effects of chronic browsing on life‐history traits of an irruptive large herbivore population
Population Ecology, EarlyView.This study aimed to determine the relationship between diet quality, body mass, and size (hind foot length), and female reproduction and sought to identify the mechanism by which high density under severe food limitations is maintained. Our results demonstrated that sika deer introduced to Nakanoshima Island have maintained high densities through high ...

Stochastic Extreme Wind Speed Modeling and Bayes Estimation under the Inverse Rayleigh Distribution
Applied Sciences, 2020 Inverse Rayleigh probability distribution is shown in this paper to constitute a valid model for characterization and estimation of extreme values of wind speed, thus constituting a useful tool of wind power production evaluation and mechanical safety of

On testing exponentiality under Type-I censoring
Frontiers in Applied Mathematics and Statistics, 2023 Two new goodness-of-fit testing procedures are introduced to test exponentiality when data are subject to Type-I censoring. We proposed four test statistics for this purpose.

Vere-Jones' Self-Similar Branching Model
, 2005 Motivated by its potential application to earthquake statistics, we study the exactly self-similar branching process introduced recently by Vere-Jones, which extends the ETAS class of conditional branching point-processes of triggered seismicity.

Population Ecology, EarlyView.This study examines the demographic dynamics of two seabird populations on Tromelin Island, 15 years after the eradication of brown rats. The results indicate that these populations are in good health and are expected to continue growing until breeding sites are saturated in about a century.
