Estimation prior value and mode

Dear professor,

I am seeking for help to get some advice on my estimation. I know it is a little too bold to ask others about such questions directly, but I have no idea after seeing the mode_check results. Could you please help me to have a look at it? (The mod file may cost about 1 minute.) Thanks in advance. (14.3 KB)

Your estimation runs to the boundary of the determinacy region. That’s where the red dots come from. You need to understand why this is the case economically.
