#' Data set on attachment anxiety in 3-person families (based on Cook, 2000)
#' 
#' The classic Cook (2000) dataset consists of measurements on security of attachment within families. 
#' Only the variable measuring fear of rejection in family relationships is included in this dataset. 
#' Cook (2000) deduced this variable from the anxiety dimension of the adult attachment scale (Collins & Read, 1990).
#' The orignial data consisted of four person families (i.e. two parents and two children), but in order to obtain  a three person family the oldest sibling is systematically deleted in accordance with Kenny, Kashy & Cook (2006).  The following labels are used for the three roles: the mother is labelled "m", the father "f" and the youngest child "y". The data are presented in the long format.
#' Three roles are present: Mothers "m", fathers "f", and the younger child "y".
#'
#' The variables are as follows:
#' 
#' \itemize{
#'   \item family.id An indicator for the family.
#'   \item actor.id An indicator of the rater in the dyad, either "m", "f", or "y"
#'   \item partner.id An indicator for the person being rated in the dyad, either "m", "f", or "y"
#'   \item anx1: First indicator of relationship specific anxiety (i.e. average of first halve of the scale).
#'   \item anx2: Second indicator of relationship specific anxiety (i.e. average of second halve of the scale).
