In our model below when we run it, the Attribute 'Seedlings' does not give choice of '10 or 20' in any scenario. There are '0 and 10' and '10 and 10' and '0 and 20' etc but no 10 and 20. We have tried with a number of designs with different priors etc and the same. Can you explain why?
Design
;alts = alt1*, alt2*, OptOut
;rows = 36
;block = 3
;eff = (mnl,d)
;alg = swap(stop=noimprov(120 secs))
;model:
U(alt1) =
b1[-0.001] * Seedlings[0,10,20]
+ b2.effects[-0.01] * Labor[1,2]
+ b3.effects[0.01|0] * Maturation[3,4,6]
+ b4.effects[-0.01|0] * Yield[15,25,40]
+ b5[0.001] * Price[3,5,10,15,20,40]
/
U(alt2) =
b1 * Seedlings + b2 * Labor + b3 * Maturation + b4 * Yield + b5 * Price
/
U(OptOut) = None[-0.001]
