Hi Michiel,
this is the same kind of output am getting, but for scenario 1 and 34,
atl1.test =3 and alt2.test = 3.
This means I would be comparing the same type of test.
The type of tests are 1, 2, 3 and 4.
In this case the respondent would just choose one with better attribute level yet the aim ...

Hi Michiel,
I have included the following constraints in my model but I keep getting scenarios comparing the same test, although with different levels of the remaining attributes.
What could be wrong in my syntax? I have run it over three days but get the same challenge.

design
;alts = alt1 ...

Hi Michiel,
thank you very much.
Kind regards
Norma

Hi, I need help with my utility specification, to create constraints on just one level of a given attribute.
This is my syntax
design
;alts = alt1*, alt2*
;rows = 36
;eff =(mnl,d)
;block = 4
;model:
U(alt1)= b1.dummy[0|0|0]*test[1,2,3,4] + b2.dummy[0|0|0]*risk[1,5,20,50] + b3*cost[0,50,200] + b4 ...

Thank you, Michiel. This is of great help.

Thank you Michiel, this is very helpful.

So I have revised the model as below because attribute D is dummy coded. But I get this error
Error: An attribute has the wrong number of levels for dummy or effects coding. 'd'
design
;alts(mnl_model) = alt1*, alt2*
;alts(rppanel_model) = alt1*, alt2*
;rows ...

This is my syntax
design
;alts(mnl_model) = alt1*, alt2*
;alts(rppanel_model) = alt1*, alt2*
;rows = 36
;eff = mnl_model(mnl,d)
;block = 3
;model(mnl_model):
U(alt1)= b1*A[50,60,70] + b2*B[30,50,70] + b3*C[1] + b4*D[0,1,2] +b5*E[0.25,2,5,10]/
U(alt2) = b1*A2[60,70,80] + b2*B2[25,40,50] + b3*C2[1,3 ...
