 Usage:  {edr, eigen} = sir (x, y, h)  

 

 Input:



  x                      n x p matrix, the explonatory variable 

                         

  y                      n vector, the dependent variable 

                         

  h                      scalar, number of slices (h>=2) 

                         width of slice (0 < h < 1) 

                         elements in a slice (-h) 

                         

 Output:



  edr                    p x p matrix containing estimates of the edr 

                         

  eigen                  p vector of the eigenvalues
