SAMPSIZE computes sample sizes for cohort/cross sectional
studies and for unmatched case-control studies. The
formulas used are from:

Kelsey JL, Thompson WD, and Evans AS: Methods in
Observational Epidemiology, Oxford University Press,
New York, 1986 (see tables 10-11 and 10-15)


Fleiss JL: Statistical Methods for Rates and
Proportions, John Wiley & Sons, New York, 1981 (see
formulas 3.18 and 3.19).

Sample size calculations for Population Attributable
Fraction (PAF) are based on formulae from:

Browner WS, Newman TB. Sample size and power based on
the population attributable fraction. Am J Public
Health 1989; 79:1289-1294.

Power calculations for cohort/cross sectional studies and
for case-control studies are based on:

Schlesselman JJ: Case-Control Studies, Oxford
University Press, New York, 1982 (see formula 6.9).

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read:
