#' @title Berkeley Child Guidance Study Data
#'
#' @description Data provide longitudinal growth records for 136 children.
#'
#' @details Data originally included as an appendix in the book “Physical growth
#'   of California boys and girls from birth to eighteen years" authored by
#'   \insertCite{Tuddenham1954;textual}{bsitar}, and later used as an example
#'   dataset in the \pkg{sitar} \insertCite{R-sitar}{bsitar} package after
#'   correcting for the transcription errors.
#'
#'   A detailed description of the data including the frequency of measurements
#'   per year is provided in the \pkg{sitar} package.
#'   \insertCite{R-sitar}{bsitar}. Briefly, the data comprise of repeated growth
#'   measurements made on 66 boys and 70 girls (birth to 21 years). Children
#'   were born in 1928-29 (Berkeley, California) and were of north European
#'   ancestry. Measurements were made at the following ages: 0 (i.e, at birth),
#'   0.085 year, 0.25 to 2 years (every 3 month), 2 to 8 years (annually), and 8
#'   to 21 years (6-monthly). The children were measured for height, weight
#'   (undressed), stem length, biacromial diameter, bi-iliac diameter, leg
#'   circumference, and dynamo metric strength.
