Sample size calculation for confidence intervals


This program performs calculations of the probability that a specified one-group study (specification includes sample size) will produce a
confidence interval (CI) of at most a particular length. It also calculates the sample size necessary to achieve a desired such probability.

Includes Macintosh (Intel and PowerPC) and Windows executables.

CONFINT15 will perform calculations for

  • One-sample binomial
  • One-sample Poisson
  • Mean of the One-Sample Normal
  • SD of the One-Sample Normal
  • Hazard of One-Sample Exponential Survival Distribution
  • Mean survival of the One-Sample Survival Distribution
