#' Example Dataset for a Survival Outcome with Censoring
#'
#' A dataset consisting of 11,332 observations on 2,500 individuals over 7 time points. Each row in the dataset corresponds to the record of one individual at one time point. Individuals who are censored at time \eqn{k+1} only have a total of \eqn{k+1} records, which correspond to time indices \eqn{0,..., k}.
