  1. Given two simple linear regression lines (y 1 = a 1 + b 1 x 1, y 2 = a 2 + b 2 x 2), one of which is for subjects without the Arg allele and the other is for subjects with the Arg allele
  2. b 1 − b 2, the difference between the two slopes, d, the distance between two regression lines in the case of the two regression lines being parallel
