Fictitious data designed to closely replicate the characteristics and patterns 
observed in the Africa Centre Demographic Information System (ACDIS).

Data sets used in the book Marra and Radice (2025, ISBN:9781032973111) "Copula Additive Distributional Regression Using R", for illustrating the fitting of various joint (and univariate) regression models, with several types of covariate effects, in the presence of equations' errors association.
