Environmental policy in the context of complex systems: Statistical sensitivity testing and policy optimization using agent-based models

, 1900

This paper introduces a machine-learning–assisted framework for optimizing environmental policy in complex agent-based models. By combining statistical sensitivity testing with Bayesian optimization, it enables efficient policy search despite costly simulations. Applied to an extended Sugarscape model with pollution, the approach identifies interpretable policies and reveals key tradeoffs between welfare, inequality, and survival.

Sample size calculation of SMART design with skewed outcome: Application to the SMART+ study

, 1900

In this paper, we developed sample size calculation formulas based on precision and power for the SMART design with skewed outcomes, suitable for both full-scale SMART and pilot-SMART studies.

A Semiparametric Generalized Exponential Regression Model with a Principled Distance-based Prior for Analyzing Trends in Rainfall

, 1900

In this paper, we analyzed of precipitation data in the Western Ghats region from 1901 to 2022 by developing a semiparametric GE regression model that extends the GE distribution to a regression setting. We also constructed a novel class of penalized complexity prior for the shape parameter of the GE distribution.
