Apologies for reposting this question and thanks for your suggestions about this couple of days ago.
You suggested that the lower bound of the scale parameter should not be negative, which I did wrong at first.
I tries with other non-negative lower bound values, but still, the model is unidentified.
I defined the scale parameter as:
Scale = Beta('Scale',1.45608965291534, 0,1.5,0,'Scale' ) and other non-negative values.
An example of utility function:
V1 = exp(Scale*LV_VID)*(ASC + Plantation*A1C1SFW1 + Repurposed*A1C1SFW2 + Farm*A1C1SFW3 + Poor*A1C1LFW1 + Jobs*A1C1LFW2 + Wildlife*A1C1LFW3 + Distance*A1C1DFW + EC + Cost*A1C1CFW)
where LV_VID is a latent variable.
I am grateful if you have some suggestions for me.
