Webestimate the standard errors. The present article is organized into five sections. In Sec. 2, we discuss the background of this study including GLMM and MSM. In Sec. 3, we propose a two-stage block nonparametric bootstrap method to estimate the standard errors. Simulation study is reported in Sec. 4. Finally, we give a summary in Sec. 5. 2 ... Webwhere \(\sigma^2\) is a scale parameter. Under this modification, the Fisher-scoring procedure for estimating \(\beta\) does not change, but its estimated covariance matrix becomes \(\sigma^2(x^TWx)^{-1}\)—that is, the usual standard errors are multiplied by the square root of \(\sigma^2\). This will make the confidence intervals wider.
