In mice: Multivariate Imputation by Chained Equations

#' Fifth Dutch growth study 2009
#'
#' Age, height, weight and region of 10030 children measured within the Fifth
#' Dutch Growth Study 2009
#'
#' The data set contains data from children of Dutch descent (biological parents
#' are born in the Netherlands). Children with growth-related diseases were
#' excluded. The data were used to construct new growth charts of children of
#' Dutch descent (Schonbeck 2013), and to calculate overweight and obesity
#' prevalence (Schonbeck 2011).
#'
#' Some groups were underrepresented.  Multiple imputation was used to create
#' synthetic cases that were used to correct for the nonresponse. See Van Buuren
#' (2012), chapter 8 for details.
