Warning message in pec function using rfsrc model in R
I have used Random Survival Forest function from randomForestSRC
package on a traindata and then to calculate Brier Score on testing set I have used pec
function from pec
package as follows:
PredError <- pec::pec(object=model,
formula=frmla, cens.model="cox",
data=testdata, verbose=F, maxtime=1000,testIBS=TRUE)
The function returns this warning message:
In fitter(X, Y, strata = Strata, offset = offset, weights = weights, :
Ran out of iterations and did not converge
Can someone help me to understand the meaning?
r warnings survival-analysis

Usually fitter functions have an niter or iter.max that can be increased.
