#' Analytical skills of young gifted children
#'
#' An investigator is interested in understanding the relationship, if any,
#' between the analytical skills of young gifted children and the following
#' variables: father's IQ, mother's IQ, age in month when the child first said
#' "mummy" or "daddy", age in month when the child first counted to 10
#' successfully, average number of hours per week the child's mother or father
#' reads to the child, average number of hours per week the child watched an
#' educational program on TV during the past three months, average number of
#' hours per week the child watched cartoons on TV during the past three
#' months. The analytical skills are evaluated using a standard testing
#' procedure, and the score on this test is used as the response variable.
#'
#' Data were collected from schools in a large city on a set of thirty-six
#' children who were identified as gifted children soon after they reached the
#' age of four.
