Rather than cite particular techniques I quote the abstract of this article which will show how useful it can be. ‘Statistical malpractice is an insidious, and indeed prestige-laden and grant-rewarded activity. Brilliantly clever, but fundamentally wrong-headed, number-crunchers are encouraged to devise inappropriate applications of mathematical methods to health problems. This species of misdirected zealot has so far been immune from criticism.’.
