Examples

Every example exists in both a Python version (hecfdapy, a Jupyter notebook you can download and run) and an R version (hecfdar, a Quarto document). Each one reproduces a value validated against the real HEC-FDA C#, and states that value alongside the result it computes.

• 00 – Getting started: install both packages and reproduce the deterministic 150000 EAD oracle from the quick start above.
• 01 – Distributions: density, CDF, quantile, and seeded sampling across the 13 ported distribution families.
• 02 – Stage-damage curves: build a structure inventory and compute a stage-damage curve, checked against the tractable Residential/Commercial oracle.
• 03 – EAD simulation: run the seeded Monte Carlo expected annual damage simulation for one impact area and reproduce the exact-100-iteration benchmark.
• 04 – Alternatives capstone: chain a scenario through EqAD annualization and with/without-project benefits, reproducing the full AlternativeComparisonReport pipeline.
