#' The Berkeley Child Guidance Study
#'
#' The Berkeley Child Guidance Study dataset contains longitudinal anthropometry
#' data for 136 children from birth to 21 years.
#'
#' The data are for 66 boys and 70 girls from Berkeley, California born in
#' 1928-29 of north European ancestry, and followed from birth to 21 years.
#' Measurements were at ages 0, 0.085, 0.25 to 2 (3-monthly), 2 to 8 (annually),
#' and 8 to 21 (6-monthly) years.
#'
#' The children were measured for height, weight (undressed), stem length,
#' biacromial diameter, bi-iliac diameter, leg circumference, and dynamometric
#' strength. The data were provided as an appendix to the book by Tuddenham and
#' Snyder (1954), and a few transcription errors are corrected here. A further
#' 19 errors in height and weight as reported in \code{sitar} issue #7 are also
#' now corrected. The \code{growth} dataset in the \code{fda} package uses
#' heights from the same study.
