2016-06-20 Thread Andreu Ferrero
Hey, I am using "frailtyPenal" to fit a general joint model: I got a "Model did not converge" message, and I guess it is because I miss specify something in the command: "Call: frailtyPenal(formula = Surv(Time_final_mes_cor, BD_RE2.Re_IC1_cor) ~ cluster(BD_RE2.e_b_id) +

I wanted to provide a follow-up post regarding the question of the coxme program and nested (multilevel) frailty analysis. As it turns out, my failure to produce results was a result of my own error. The following syntax seems to successfully produce results for a model accounting for both

I can't comment on frailtypack issues, but would like to mention that coxme will handle nested models, contrary to the statement below that frailtypack is perhaps the only for nested survival data. To reprise the original post's model cgd.nfm - coxme(Surv(Tstart, Tstop, Status) ~

Hello everyone, I have a question about using frailtypack to run recurrent events data. I have a file with 1,580 events. The file structure fits the andersen gill model. When I run the file with all records, the R stops and shuts down. Once I run only part of the file, about 400 events, R runs
