Pfeifer Applied Statistics Group Engineering Department Louviers Building . I, du Pont de Nemours & Company Wilmington, Delaware 19898 Dear Dr. Pfeifer: This is a belated note of thanks for your letter of February 15 and the enclosures related to the NHANES II data. It was interesting to read these comments and to see the major areas of overlap with reviews with which I had been involved. My activity in this matter seems to be on hold for the moment, but if it is necessary to go through this material in detail, I may have some questions. It is amazing how people continue to seek conclusions, particularly if they suit their goals, on the basis of correlations that are probably spurious and caused by companion time trends. I do thank you for your courtesy in providing this material. Yours sincerely, RAB/dt cc: Or. R, D, Snee Ralph A.
