 Usage:  {val, df, pval} = haztest(data, index)  

 

 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. 

                         

  index                  p x 1 vector, with ith element = 0 when beta_i = 0 

                         is in the null hypothesis, and 1, otherwise. 

                         

 Output:



  val                    3 x 1 vector, values of the test statistics. 

                         

  df                     scalar, degree of freedom. 

                         

  pval                   3 x 1 vector, P-values of the tests.
