#' Background data of 8 groups from a longitudinal
#' study on Dutch primary schools
#' 
#' Background data of the children, complementary to the files with the rating
#' data Ss96.rat, Ss97.rat and Ss98.rat. This data file contains 205
#' observations of 4 variables. Measurements of these Dutch primary school
#' children were taken three times, in 1996, 1997 and 1998. In 1996, the sample
#' consisted of 193 students (91 boys, 96 girls, six gender unknown); 189
#' students were involved in 1997 (90 boys, 95 girls, 4 gender unknown); and in
#' 1998, 189 students participated (91 boys, 98 girls). Average age in 1998 was
#' 11.3 years, with ages ranging from 11 to 13 years. The participants were
