A Copula-Based Model for Analyzing Bivariate Offense Data Open
We developed a class of bivariate integer-valued time series models using copula theory. Each count time series is modeled as a Markov chain, with serial dependence characterized through copula-based transition probabilities for Poisson an…

A Copula Discretization of Time Series-Type Model for Examining Climate Data Open
The study presents a comparative analysis of climate data under two scenarios: a Gaussian copula marginal regression model for count time series data and a copula-based bivariate count time series model. These models, built after comprehen…

Review of Copula for Bivariate Distributions of Zero-Inflated Count Time Series Data Open
The class of bivariate integer-valued time series models, described via copula theory, is gaining popularity in the literature because of applications in health sciences, engineering, financial management and more. Each time series follows…

A Class of Copula-Based Bivariate Poisson Time Series Models with Applications Open
A class of bivariate integer-valued time series models was constructed via copula theory. Each series follows a Markov chain with the serial dependence captured using copula-based transition probabilities from the Poisson and the zero-infl…
