hello,everyone:
  I am now confused in multistate survival , when I want to poccess a  multistate survival analysis, I turn to R and the package 'mstate'  and packege 'cmprsk'. When I come to publishing the article.
Follow  requirement  of the magzine, the statistic is carry out in LTA package (which was said  to be a authority in intauterine from WHO) . There we found difference in the results(incidence ratio or survival function) computed by the two software. I also come to the result from SAS, carry out survival analysis for each cause seperately using prod-limit method,. the result is closed to LTA rather than R.
why ? is the result from R better than LTA or carry out survival analysis for each cause seperately using prod-limit method?
thanks a lot!
sincerecely
