Dear Prof. Pfeier and Colleagues
I have develop a DSGE model and run it. Everything seems to be fine but the problem came out like this

I attempt to figure out this problem but it does not work. I attach the mod file and data here.
Any suggestion, advice is greatly appreciated.

someone can give me advice on this issue?


Is this an occasional warning that pops up for some draws? Or does it appear for every draw? If it’s the former and the results from mode finding look ok, you can ignore it.
