ERRI: Economic Resilience and Recovery Index

Estimates multidimensional economic resilience following a disruption by comparing observed outcomes with a counterfactual path. Components describe shock depth, cumulative loss, recovery time, recovery strength, post-shock stability, and positive transformation. The package supports grouped analysis, residual-bootstrap uncertainty, alternative weighting schemes, ranking probabilities, sensitivity analysis, shock screening, and diagnostic plots. Methods are designed for regional, sectoral, market, and other regularly observed economic time series.
