Thread: Random survival forests

  1. #1

    Random survival forests




    Would like to hear if any one has used this method for survival analysis. How does it compare with COX models while building a model with several (>15) variables and a small sample size (~300) patients? I feel it is not as reliable as the COX models (semi parametric and based on the assumption that the hazards are proportional).

    I have not used this, but I would appreciate it if you could provide a link to the package software and/or a good example (paper) of this in action.

    Try this one. I haven't finished reading it, so can't comment right now. Please let me know if you find another very useful article. Thanks.

    That article was too vague, just sounded like random forewst. Deference 2 and 4 appear better for detail. I may print them and take gander this weekend if I have time.

    This package seems pretty cool for finding the cutoff for continuous predictor in survival analysis. I have not stared hard enough to see if they have repeat measures of survival.
