Weight-aware imputation for policy microsimulation

Regime-gated, chained, weighted-bootstrap quantile-regression forests, benchmarked against unweighted/weighted QRF, OLS, linear quantile regression, and hot-deck matching. 21 pages.

calibrationplan stage

Gradient-descent survey calibration vs. classical calibration, at scale

Comparing modern gradient-descent calibration against raking, GREG, entropy balancing, and bounded chi-square. Plan and method scaffold only — no results yet.

The population-view harness, as a standalone referee

Energy distance, calibration-blind coverage, classifier AUC, and an uncapped tail block — proven inside imputation-paper; the standalone popdgp methods paper has not been started.
