 Usage:  inrisk = hazrisk(data,i)  

 

 Input:



  data                   n x (p+4) matrix, 

                         column 1: the sorted observed survival time t, 

                         column 2: the cosorted censoring indicator delta, 

                         column 3: labels l, 

                         column 4: number of ties at time t[i], cosorted, 

                         columns 5 to p+4: the cosorted covariate matrix z. 

                         This data matrix may be obtained through hazdat.xpl. 

                         

  i                      an integer between 1 and n. 

                         

 Output:



  inrisk                 n x 1 vector, the jth entry is 1 if the jth 

                         observation is at risk at time i, 0 otherwise.
