Hello everyone,

I am trying to fit my model with these versions

R version 4.0.2

Rstan 2.19.3

Platform: x86_64-w64-mingw32/x64 (64-bit)

In my case I am trying to looping the likelihood function(user defined function) over 1:25 with 3 chains. Initially, I tried to fit from 1 to 5 loops, and then 1: 10 loops…For those cases I could do sampling for all chains, but I failed for all loops (i.e. 1:25), it runs only chain 1 and 2 and for chain 3, it gives following error message,

SAMPLING FOR MODEL ‘585f9f35f8c48980a605c47c29c98779’ NOW (CHAIN 3).

Chain 3: Exception: integrate: error estimate of integral 7.80258e-16 exceeds the given relative tolerance times norm of integral

Could anyone help me here? I put seed =1234 in each cases.

Thanks
