     This is a numeric matrix with 69 rows and 7 columns:

       '[,1]'  'G'   Parental risk group
       '[,2]'  'D1'  Symptoms, child 1
       '[,3]'  'D2'  Symptoms, child 2
       '[,4]'  'R1'  Reading score, child 1
       '[,5]'  'V1'  Verbal score, child 1
       '[,6]'  'R2'  Reading score, child 2
       '[,7]'  'V2'  Verbal score, child 2

     The parental risk group was coded 1, 2 or 3, from low or high, and
     the child symptoms 1 = low or 2 = high.  Missing values occur on
     all variables except 'G'.
