A new statistical estimation framework based on variational inequalities (VIs) has been proposed for generalized linear models (GLMs). This VI approach offers an alternative to traditional maximum likelihood estimation (MLE), particularly for models with non-canonical, non-smooth, or saturating link functions where MLE can face computational challenges. The VI framework provides theoretical guarantees, including finite-sample error bounds and asymptotic normality, and has demonstrated competitive estimation accuracy and faster convergence in numerical experiments, especially for GLMs and generalized additive models (GAMs) with complex link functions.
