Sample Size Estimating a Single ROC : The data is in 2 columns.
- Each row a separate study
- Col 1 = ROC to be estimated θ
- Col 2 = Standard Error Required
Standard Error of a Single ROC : The data is in 3 columns.
- Each row a separate study
- Col 1 = ROC found θ
- Col 2 = Number of cases with Outcome Negative
- Col 3 = Number of cases with Outcome Positive
Sample Size Comparing Two ROCs : The data is in 4 columns.
- Each row a separate study
- Col 1 = Probability of Type I Error for Decision(α)
- Col 2 = Power (1-β)
- Col 3 and 4 = Anticipated Values of the Two ROCs
Power Estimation Comparing Two ROCs : The data is in 4 columns.
- Each row a separate study
- Col 1 = Probability of Type I Error Found(α)
- Col 2 = sample size per ROC used (Outcome pos + outcome neg)
- Col 3 and Col 4 = Observed Values of the Two ROCs
