R random survival forest predict confidence

Question

[hdy]

Hi, I am using R package 'randomForestSRC' to do survival analysis. I used rfsrc function to build the model with the training dataset. And I used predict function to get the predicted survival of the test set. It seems I can get the predicted days of survival. But is there a way to get some confidence level for each of these predictions as well?

Thanks!

Not really an answer but an idea that you could do is to vary the inputs randomly and measure the sorts of values generated. See how varied they are.
