In Kenny-Jing-Xu/survivalMPLdc: Penalised Likelihood for Survival Analysis with Dependent Censoring

#' PRIME data set
#'
#' This data set is from a longitudinal study called "Prospective Research in Memory Clinics" (PRIME),
#' see Brodaty et al (2011), with a period of 3-year. The data set includes 583 dementia patients. The
#' outcome is time to institutionalised. The predicators are age, sex, educational level, living status,
#' dementia type, baseline cognitive ability (MMSE), baseline functional ability (SMAF),
#' baseline neuropsychiatric symptoms (total NPI), baseline dementia severity (CDR),
#' baseline caregiver burden (ZBI), medication types, change in cognitive ability at 3 months,
#' change in functional ability at 3 months, and change in neuropsychiatric symptoms at 3 months.
#' Note that this data set is complete and was analyzed by Brodaty et al (2014).
