Hi everyone,
I encountered a problem using the coxph function for the conditional
logistic regression. I am trying to do some simulations and I really donât
understand a mistake which happened maybe only 1 time among more than
1,000 simulations.
What appeared on the screen is the following:
Error in fitter(X,Y,strats,offset,init,control,weights=weights,:
NA/NaN/Inf in a foreign function (arg 6)
Warning message:
Ran out of iterations and did not converge in:
fiiter(X,Y,strats,offset,init,control,weights=weights,
I donât know if the warning message could have caused the error or vice
versa.
Does anyone have just an idea of what kind of error it can be? I donât put
all the code because it is very long. But I guess that this error message
may have an "answer" whatever the code is?
Thanks so much in advance!
Willy
