A Seasonal Transmuted Geometric INAR Process: Modeling and Applications in Count Time Series
MathematicsIn this paper, the authors introduce the transmuted geometric integer-valued autoregressive model with periodicity, designed specifically to analyze epidemiological and public health time series data. The model uses a transmuted geometric distribution as

On quasi Pólya thinning operator
, 2023 International audienceThinning operation is a stochastic operation that shrinks a random count variable into another one. This kind of random operation has been intensively studied during the seventies to characterize some count distributions, such as ...

Risk management externalities in agrifood supply chains
American Journal of Agricultural Economics, EarlyView.Abstract Firms may under‐ or over‐invest in risk management from the social planner's perspective, resulting in a negative externality on other economic agents in the supply chain. The externality of risk management is particularly relevant for agrifood supply chains, which frequently experience disruptions and play a primary role in preventing major ...

Randomness Test of Thinning Parameters for the NBRCINAR(1) Process
AxiomsNon-negative integer-valued time series are usually encountered in practice, and a variety of integer-valued autoregressive processes based on various thinning operators are commonly used to model these count data with temporal dependence. In this paper,

On Hitting Times for Markov Time Series of Counts with Applications to Quality Control
Revstat Statistical Journal, 2016 Examples of time series of counts arise in several areas, for instance in epidemiology, industry, insurance and network analysis. Several time series models for these counts have been proposed and some are based on the binomial thinning operation ...
