%description
Provides functions to model and forecast crop yields using a spatial
temporal conditional copula approach. The package incorporates extreme
weather covariates and Bayesian Structural Time Series models to analyze
crop yield dependencies across multiple regions. Includes tools for
fitting, simulating, and visualizing results. This method build upon
established R packages, including 'Hofert' 'et' 'al'. (2025)
