Input Data
Sample Size :The data is in 4 columns
  - Each row a separate calculation
  - Col 1 = probability of Type I Error (α)
  - Col 2 = Power (1-β)
  - Col 3 = number of independent variables u
  - Col 4 = expected Multiple Correlation Coefficient R
  

Power Estimation : The data is in 4 columns.
  - Each row a separate calculation
  - Col 1 = probability of Type I error α
  - Col 2 = sample size in the study
  - Col 3 = number of independent variables u
  - Col 4 = observed multiple correlation coefficient R
