Hi, I´m trying to use the calibrate function from rms package (made by prof. Harrell) after fitting a model using cph. But it returns the following error message:
> calibrate(modelo1,B=200,bw=F,u=13) Using Cox survival estimates at 13 Days Convergence problems.... stopping addition Error in hare(S[, 1], S[, 2], fun(est.surv), maxdim = maxdim, ...) : no convergence this is serious! Has anybody experienced the same problem? Can anyone help me? many thanks, Rodrigo -- View this message in context: http://n4.nabble.com/Problem-with-calibrate-function-tp961100p961100.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
