I am trying to do survival analysis in matlab and want to calculate log rank test scores among several curves. I found a possible code to do log rank here. But based on its description, it can only do log rank test between two groups. What if I have 3 or more curves?

  • can't you perform pair-wise tests? – Buck Thorn Mar 09 '15 at 15:02
  • I can perform pair-wise tests, then I get multiple p values from log rank test. How can I combine all those into one? Take average? – lolibility Mar 09 '15 at 15:06
