%description
Implements a structured, reproducible framework for budget impact
modelling (BIM) in health technology assessment (HTA), following the ISPOR
Task Force guidelines (Sullivan et al. (2014)
<doi:10.1016/j.jval.2013.08.2291> and Mauskopf et al. (2007)
<doi:10.1111/j.1524-4733.2007.00187.x>). Provides functions for
epidemiology-driven population estimation, market share modelling with
flexible uptake dynamics, per-patient cost calculation across multiple
cost categories, multi-year budget projections, payer perspective
analysis, deterministic sensitivity analysis (DSA), and probabilistic
sensitivity analysis (PSA) via Monte Carlo simulation. Produces
submission-quality outputs including ISPOR-aligned summary tables,
scenario comparison tables, per-patient cost breakdowns, tornado diagrams,
PSA histograms, and text and HTML reports compatible with NICE, CADTH, and
EU-HTA dossier formats. Ships with an interactive 'shiny' dashboard built
on 'bslib' for point-and-click model building and exploration.
