%description
Implements Doubly Robust Matching-Adjusted Indirect Comparison (DR-MAIC)
for population-adjusted indirect treatment comparisons in health
technology appraisal (HTA). The package provides: (1) standard MAIC via
entropy balancing / exponential tilting; (2) augmented/doubly robust MAIC
combining inverse probability weighting with outcome regression; (3)
comprehensive covariate balance diagnostics including standardised mean
differences, Love plots, and effective sample size; (4) sensitivity
analyses including E-values, weight trimming, and variable exclusion
analyses; (5) bootstrap confidence intervals; and (6) submission-ready
outputs aligned with NICE Decision Support Unit Technical Support Document
18, Cochrane Handbook guidance on indirect comparisons, and ISPOR best
practice guidelines. Supports binary (risk difference, risk ratio, odds
ratio) and time-to-event (hazard ratio) outcomes.
