#' Simulated dataset simdataHADS
#'
#' The data mimic the PREDIALA study described and analyzed in Proust-Lima et al (2021 -
#' https://arxiv.org/abs/2109.13064).
#' The study aims to describe the trajectories of depressive symptomatology of patients
#' suffering end-stage renal disease and registered on the renal transplant waiting list.
#' Repeated measures of anxiety and depression (HADS) were simulated at different times
#' of measurement for 561 subjects. Four time-independent covariates were also generated:
#' group (dialyzed or pre-emptive), sex and age at entry in the cohort and time on the
#' waiting list at entry in the cohort.
