Claim 3:
4. The method of claim 3, wherein the coefficient of determination is computed based on a squared coefficient of multiple correlation as follows:, R
   2
  
  =
  
   1
   -
   
    
     
      ∑
       
     
     
      i
      =
      1
     
     n
    
    ⁢
    
     
      (
      
       
        D
        i
       
       -
       
        A
        i
       
      
      )
     
     2, where R2 is the coefficient of determination having a value between 0 and 1, Di is the time-series value at the ith position in the time-series signal, Ai is the value of the time-series representation at the ith position, and, ∑
     
   
   
    i
    =
    1
   
   n
  
  ⁢
  
   
    (
    
     
      D
      i
     
     -
     
      A
      i
     
    
    )
   
   2, is a sum of the squared residuals.
