#' Holzinger and Swineford data
#'
#' The Holzinger and Swineford dataset \insertCite{Holzinger1939}{cSEM} 
#' consists of mental
#' ability test scores of seventh- and eighth-grade children from two
#' different schools (Pasteur and Grant-White). In the original dataset
#' (available in the \pkg{MBESS} package), there are scores for 26 tests.
#' The present dataset is taken from \pkg{lavaan} and consists of a smaller 
#' subset with 9 variables that is more widely used in the 
#' literature (e.g., \insertCite{Joereskog1969;textual}{cSEM}).
