  Data generating mechanism for the "illustrative example" in 
  Technometrics 48, 491--502, Sec 1.2, 2.1 and 4.3 (variation 0):
  n =  40, p =  20, y =  x5 + 2*x10 + 3*x15 + epsilon, epsilon ~ N(0,1).

  Data generating mechanism for this movie: 
  n = 120, p = 100, y = x20 + 2*x50 + 3*x80 + epsilon, epsilon ~ N(0,1).

  That is, the movie here is for an example that is much larger than 
  but otherwise identical to the one in the original paper.
