 Usage:  {bhaz, bsurv} = hazbase(data)  

 

 Input:



  data                   n x (p+4) matrix, the first column is the sorted 

                         survival time t, followed by the sorted delta, 

                         inidcating if censoring has occured, labels l, a 

                         column containing the number of ties, and lastly, 

                         the sorted covariate matrix z. 

                         

 Output:



  bhaz                   n x 2 matrix, the first column is the sorted 

                         t, followed by the estimated baseline hazard 

                         function at the points of t. 

                         

  bsurv                  n x 2 matrix, the first column is the sorted 

                         t, followed by the estimated baseline survival 

                         function at the points of t.
