WebGeneralized linear mixed models (GLMMs) are typically constructed by incorporating random effects into the linear predictor. The random effects are usually assumed to be normally distributed with mean zero and variance-covariance identity matrix. WebSep 20, 2024 · Our generalized Newton methods provide a tool for enlarging the region where \lambda =\lambda (s) is finite. Moreover, a suitable choice of s might produce a smaller value \lambda (s), thus resulting in an improvement of the convergence speed. We illustrate this phenomenon in Sect. 4.
