Estimation for Binary Emax Models with Missing Responses and Bias Reduction // Provides estimation utilities for binary Emax dose-response models. Includes Expectation-Maximization based maximum likelihood estimation when the binary response is missing, as well as bias-reduced estimators including Jeffreys- penalized likelihood, Firth-score, and Cox-Snell corrections.The methodology is described in Zhang, Pradhan, and Zhao (2025) doi:10.1177/09622802251403356 and Zhang, Pradhan, and Zhao (2026) doi:10.1080/10543406.2026.2627387.
