Description: Provides likelihood-based inference for Gaussian and Student-t 
    copula models for univariate count time series. Supports Poisson, 
    negative binomial, binomial, beta-binomial, and zero-inflated 
    marginals with ARMA dependence structures. Includes simulation, 
    maximum-likelihood estimation, residual diagnostics, and predictive 
    inference. Implements Time Series Minimax Exponential Tilting (TMET) 
    <doi:10.1016/j.csda.2026.108344>, an adaptation of minimax exponential 
    tilting of Botev (2017) <doi:10.1111/rssb.12162>. Also provides a 
    linear-cost implementation of the Geweke–Hajivassiliou–Keane (GHK) 
    simulator following Masarotto and Varin (2012) <doi:10.1214/12-EJS721>, 
    and the Continuous Extension (CE) approximation of Nguyen and 
    De Oliveira (2025) <doi:10.1080/02664763.2025.2498502>. The package 
    follows the S3 design philosophy of 'gcmr' but is developed independently.
