Issue with inla.group.cv

[Dominique Soudant]

Hello,

Before May 19, 2026, the following code

LeaveGroupOut <- inla.group.cv(Smoothing, num.level.sets = 3)

did not generate any errors. I then installed R 4.6 and, as a result, reinstalled R-INLA, and now I get the following message:

        GitId: "devel"
        Error:21 Reason: This should not happen
        Message: Condition `0 == 1' is not TRUE
        Line:7992 Function: loglikelihood_generic_surv



        GitId: "devel"
        Error:21 Reason: This should not happen
        Message: Condition `0 == 1' is not TRUE

  If this does not help, please contact the developers at <he...@r-inla.org>.
De plus : Message d'avis :

Thank in advance for your help.

we are not on R-4.6 yet...

do you have the code/data that generate this? its a weird error that kind of
indicate that 4.6 behaves different from 4.5

what OS are you on? I presume you're on the latest testing version, otherwise
please upgrade

The code is only LeaveGroupOut <- inla.group.cv(Lissage, num.level.sets = 3)

and I gave a link to download Lissage. 

I'm on Ubuntu 24.04 with a tower and ubuntu 22.04 with a laptop. 

For both :

thx; found it. my bad. this was a new internal feature computing PIT for cv, but
forgot to check if the PIT is computable for that likelihood... the cencored
log-normal (or survival likelihood) is not, due to the cencoring

I'll make a new version asap
