Sample Size : The data is in 5 columns.

  • Each row a separate calculation
  • Col 1 = probability of Type I error (α)
  • Col 2 = power (1-β)
  • Col 3 = expected proportion in control cases (λc)
  • Col 4 = expected proportion in indexed cases (λi)
  • Col 5 = Ratio of control (nc) to indexed (ni) cases (r = nc/ni)

Power Estimation : The data is in 5 columns.

  • Each row a separate calculation
  • Col 1 = probability of Type I error (α)
  • Col 2 = number of paired units in the study
  • Col 3 = observed proportion in control cases (λc)
  • Col 4 = observed proportion in indexed cases (λi)
  • Col 5 = Ratio of control (nc) to indexed (ni) cases (r = nc/ni)
