%description
Provides tools for building decision and cost-effectiveness analysis
models. It enables users to write these models concisely, simulate
outcomes—including probabilistic analyses—efficiently using optimized
vectorized processes and parallel computing, and produce results. The
package employs a Grammar of Modeling approach, inspired by the Grammar of
Graphics, to streamline model construction. For an interactive graphical
user interface, see 'DecisionTwig' at
<https://www.dashlab.ca/projects/decision_twig/>. Comprehensive tutorials
and vignettes are available at <https://hjalal.github.io/twig/>.
