when I estimated a model,it shows the information in the following,

how i can solve it?

could anyone help me?

…

MH: Multiple chains mode.

MH: Searching for initial values…

MH: I couldn’t get a valid initial value in 100 trials.

MH: You should Reduce mh_init_scale…

MH: Parameter mh_init_scale is equal to 0.400000.

MH: Enter a new value… 0.2
