%description
Gaussian copula models for count time series. Includes simulation
utilities, likelihood approximation, maximum-likelihood estimation,
residual diagnostics, and predictive inference. Implements the Time Series
Minimax Exponential Tilting (TMET) method, an adaptation of Minimax
Exponential Tilting (Botev, 2017) <doi:10.1111/rssb.12162> and the
Vecchia-based tilting framework of Cao and Katzfuss (2025)
<doi:10.1080/01621459.2025.2546586>. Also provides a linear-cost
implementation of the Geweke–Hajivassiliou–Keane (GHK) simulator inspired
by 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 structure
of 'gcmr', but all code in 'gctsc' was developed independently.
