#' Terneuzen birth cohort
#'
#' Data of subset of the Terneuzen Birth Cohort data on child growth.
#'
#' This \code{tbc} data set is a random subset of persons from a much larger
#' collection of data from the Terneuzen Birth Cohort. The total cohort
#' comprises of 2604 unique persons, whereas the subset in \code{tbc} covers 306
#' persons. The \code{tbc.target} is an auxiliary data set containing two
#' outcomes at adult age. For more details, see De Kroon et al (2008, 2010,
#' 2011).  The imputation methodology is explained in Chapter 9 of Van Buuren
#' (2012).
