Data Input for Sample Size is a table of 5 columns
    Each row contains data from a separate study
    Col 1 = Probability of Type I Error α for power analysis
    Col 2 = Power (1 - β)
    Col 3 = expected Proportion
    Col 4 = Critical Difference, the tolerated limit of difference to be considered trivial
    Col 5 = φ ratio of sample sizegroup 2 / sample sizegroup 1

Data Input for Analysis is a table of 6 columns
    Each row contains data from a separate study
    Col 1 and 2 = Numbers with Positive Attributes in Group 1 and Group 2
    Col 3 and 4 = Numbers with Negative Attributes in Group 1 and Group 2
    Col 5 = Probability of Type I Error α for power analysis
    Col 6 = Critical Difference, the tolerated limit of difference to be considered trivial
