Hello,
In connection with the discussion a couple of weeks ago about using
astrological sign as a predictor variable,
I provide below the reference to Professor Peto's use of subgrouping
by astrological sign to illustrate the hazards
of free-wheeling subgroup analysis:
ISIS-2 (Second Interational Study of Infarct Survival) Group.
Randomized trial of intravenous streptokinase, oral aspirin,
both, or neither, among 17187 cases of suspected acute myocardial
infarction: ISIS-2. Lancet 1988;ii:349-360.
Let it serve a warning to the star-crossed.
Cheers,
David
