Fractional non-homogeneous Poisson and Pólya-Aeppli processes of order k and beyond. [PDF]
, 2021 We introduce two classes of point processes: a fractional non-homogeneous Poisson process of order k and a fractional non-homogeneous Pólya-Aeppli process of order k: We characterize these processes by deriving their non-local governing equations.

Polynomial Poisson algebras: Gel'fand-Kirillov problem and Poisson spectra [PDF]
, 2014 We study the fields of fractions and the Poisson spectra of polynomial Poisson algebras. First we investigate a Poisson birational equivalence problem for polynomial Poisson algebras over a field of arbitrary characteristic.

Occurrence analysis of daily rainfalls through non-homogeneous Poissonian processes [PDF]
Natural Hazards and Earth System Sciences, 2011 A stochastic model based on a non-homogeneous Poisson process, characterised by a time-dependent intensity of rainfall occurrence, is employed to explain seasonal effects of daily rainfalls exceeding prefixed threshold values. The data modelling has been

A test for superadditivity of the mean value function of a non-homogeneous Poisson process [PDF]
, 1974 Let N(t) be a non-homogeneous Poisson process with mean value function Λ(t) and rate of occurrence λ(t). We propose a conditional test of the hypothesis that the process is homogeneous, versus alternatives for which the mean value function is ...

Journal of Probability and Statistics, 2011 In this work, a class of multidimensional stochastic hybrid dynamic models is studied. The system under investigation is a first-order linear nonhomogeneous system of Itô-Doob type stochastic differential equations with switching coefficients.

Generating a non-homogeneous Poisson process
, 2012 Consider a Poisson process , with non-homogeneous intensity . Here, we consider a deterministic function, not a stochastic intensity. Define the cumulated intensity in the sense that the number of events that occurred between time and is a random ...

Compound and Non Homogeneous Poisson Software Reliability Models [PDF]
, 2023 The efficiency of two Software Reliability growth models are analyzed. The most popular based on a non homogeneous Poisson process and the less known based on a compound Poisson process. Several experimental data are used in order to analyze the goodness

The nhppp package for simulating non-homogeneous Poisson point processes in R.
PLoS ONEWe introduce the nhppp package for simulating events from one dimensional non-homogeneous Poisson point processes (NHPPPs) in R fast and with a small memory footprint.

A Counting Process Approach for Trend Assessment of Drought Condition
Hydrology, 2019 This paper discusses some methodological aspects of the historical analysis of drought, particularly the trend assessment. The Standardized Evapotranspiration Index (SPEI) is widely used as a measure of drought condition.

Fractional non-homogeneous counting process
, 2023 A new fractional non-homogeneous counting process has been introduced and developed using the Kilbas and Saigo three-parameter generalization of the Mittag-Leffler function. The probability distribution function of this process reproduces for certain set
