"Inla program failed" error with competing risks model

[Drew N]

Hi All,

I'd appreciate help with troubleshooting fitting a competing risks model. I've attached the data, where readmission1 = event for readmission, death2 = event for death, and readdeath_time = time to event and sexo is a covariate. 

Here is my model specification: 

compreaddeathmod<-joint(formSurv=list(inla.surv(time=readdeath_time,event=readmission1)~sexo,inla.surv(time=readdeath_time,event=death2)~sexo),basRisk=rep("weibullsurv",2),dataSurv=dat,control=list(priorFixed=list(mean=0,prec=(1/((log(5)/1.96)^2)))))
summary(compreaddeathmod)

The error I receive is: 

*** inla.core.safe: The inla program failed, but will rerun in case better initial values may help. try=1/1 Error in inla.core.safe(formula = formula, family = family, contrasts = contrasts, : The inla program call crashed. The inla program failed and the maximum number of tries has been reached.

Thank you in advance! 

Best,

Drew

Hi Drew,

I can see some exact zeros in your outcome, which is not compatible with the Weibull distribution.

Thank you so much Denis. Silly me!
