The aim of this investigation was to identify important factors foroutcome using a random survival forest (RSF) approach. Materials and Methods: Data were collected from 128 gastriccancer patients through a historical cohort study in Hamedan-Iran from 2007 to 2013. The event under consideration wasdeath due to gastric cancer. The random survival forest model in R software was applied to determine the key factorsaffecting survival. Four split criteria were used to determine importance of the variables in the model including log-rank,conversation?? of events, log-rank score, and randomization. Efficiency of the model was...
