Collision prediction models using multivariate Poisson-lognormal regression

open access: closedAccident Analysis & Prevention, 2009
This paper advocates the use of multivariate Poisson-lognormal (MVPLN) regression to develop models for collision count data. The MVPLN approach presents an opportunity to incorporate the correlations across collision severity levels and their influence on safety analyses.

Maximum likelihood fitting of the Poisson lognormal distribution

open access: closedEnvironmental and Ecological Statistics, 2007
In this paper some properties and analytic expressions regarding the Poisson lognormal distribution such as moments, maximum likelihood function and related derivatives are discussed. The author provides a sharp approximation of the integrals related to the Poisson lognormal probabilities and analyzes the choice of the initial values in the fitting ...

Poisson-Lognormal Distributions

open access: closed, 2018
The Poisson-lognormal distribution was suggested as a model for commonness of species by Preston. The analysis leading him to suggest this distribution was as follows: Suppose that the number of each species caught in a trap is assumed to be a single sample from a Poisson distribution with mean λ.

Performance analysis of poisson cellular networks with lognormal shadowed Rayleigh fading

open access: closed2014 IEEE International Conference on Communications (ICC), 2014
This paper analyzes downlink coverage probability and spectral efficiency of Poisson cellular networks with lognormal shadowed Rayleigh fading, provided each user is associated to the closest base station (BS). Both location-dependent and cell area wide aspects of the coverage probability and spectral efficiency metrics are presented.

Pendekatan Compound Poisson-Lognormal untuk Estimasi Kerugian Agregat dan Manajemen Modal Pada Asuransi Kendaraan

open access: closedSAINSTECH: JURNAL PENELITIAN DAN PENGKAJIAN SAINS DAN TEKNOLOGI
Model kerugian agregat tahunan asuransi kendaraan menggunakan pendekatan Compound Poisson-Lognormal untuk mendukung perencanaan Risk-Based Capital (RBC), penentuan premi, dan strategi reasuransi. Parameter distribusi frekuensi klaim (Poisson) dan severitas klaim (Lognormal) diestimasi dari data historis, lalu digunakan dalam simulasi Monte Carlo untuk ...

On Poisson Mixture of Lognormal Distributions

Lobachevskii Journal of Mathematics, 2020
Generally, jump-diffusion processes used in finance are confined to the processes with Brownian motion, constant trend and jump component, described by compound Poisson processes (CPP). CPP is usually defined by a sum of standard normal distributions. In most applications one either needs moments or characteristic function of the process.
