#'  \item{y}{The outcomes generated from Bernoulli distribution with three repeated measurements from each subject. The data is longitudinal dropout and missing at random.}
#'  \item{x}{A full covariate matrix. The first column corresponds to the intercept; the second column contains time-independent continuous-scale variable x1; the third column contains a doctor-visit variable x2; the third column contains time-independent binary-scale variable x3.}
#'  \item{x_mis}{A covariate matrix for missing data model. The first column corresponds to the intercept; the second column contains continuous variable x_mis1.}
#'  \item{id}{A vector indicating subject id.}
#'  \item{obs_ind}{A vector indicating observations for each record: 1 for observed records, and 0 for unobserved records.}
