mice: Multivariate Imputation by Chained Equations

#' SE Fireworks disaster data
#'
#' Multiple outcomes of a randomized study to reduce post-traumatic stress.
#'
#' Data from a randomized experiment to reduce post-traumatic stress by two
#' treatments: Eye Movement Desensitization and Reprocessing (EMDR)
#' (experimental treatment), and cognitive behavioral therapy (CBT) (control
#' treatment). 52 children were randomized to one of these two treatments.
#' Outcomes were measured at three time points: at baseline (pre-treatment, T1),
#' post-treatment (T2, 4-8 weeks), and at follow-up (T3, 3 months). For more
#' details, see de Roos et al (2011).  Some person covariates were reshuffled.
#' The imputation methodology is explained in Chapter 9 of van Buuren (2012).
