The percentage bend correlation between two variables X and Y is computed as follows:

• Set m = (1-n) + 0.5. Round m down to the nearest integer.
  
• Let for i = 1, ..., n where Mx. is the median of X.
  
• Sort the Wi in ascending order.
  
• = W(m) (i. e., the mth order statistic). W(m) is the estimate of the (1-) quantile of W.
  
• Sort the X values. Compute the number of values of that are less than -1 and the number that are greater than +1 and store in i1 and i2 respectively. Then compute
  
  
  
  
  
• Repeat the above calculations on the Y variable. Store corresponding quantities in , , and Vi.
  
• Define the function
  
  
  
• Compute
  
  
  Ai = i (Ui)
  Bi = i (Vi)
  
• Compute the percentage bend correlation
  
  

The value of is selected between 0 and 0.5. Higher values of result in a higher breakdown point at the expense of lower efficiency.
