Sample Size Estimate Single ROC
    

Standard Error Estimate Single ROC
    

Sample Size Compare Two ROCs
    

Power Estimate Compare Two ROCs
    
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
