 Usage:  subcs = prune (cs, alfa)  

 

 Input:



  cs                     list of vectors: data structure which represents a binary 

                         tree and is produced by cartsplit procedure, contains vectors 

                         cs.val, cs.vec, cs.mean, cs.ssr, cs.nelem. 

                         See cartsplit for the description of cs. 

                         

  alfa                   real number >= 0: the tree subcs is the subtree 

                         of cs which minimizes the error-complexity criterion 

                         with the complexity parameter alfa. 

                         

 Output:



  subcs                  similar kind of object than cs, see cartsplit for the 

                         description of subcs. The tree subcs is the subtree of cs 

                         which minimizes the error-complexity criterion when the 

                         complexity parameter is alfa.
