An expectation-maximization algorithm for logistic regression based on individual-level predictors and aggregate-level response

Xu, Zheng - In: Statistics in transition : an international journal of … 26 (2025) 1, pp. 9-28

Logistic regression is widely used in complex data analysis. When predictors are at individual level and the response at aggregate level, logistic regression can be estimated using the Maximum Likelihood Estimation (MLE) method with the joint likelihood function formed by Poisson binomial...
