Result change drastically when increase halton draws from 1500 to 2000 draws
Posted: 14 Mar 2023, 13:29
Hi Stehane,
I am considering log-normal distribution in all these results. Why am I getting NaN when I increase the Halton draws to 2000? Also, the parameter estimates change drastically when I change the number of Halton draws from 1500 to 2000.
Thanks
