Dear all,

I am running the following explicit partial profile design, using a candidate set and restrictions:

Design
;alts = progA, progB
;rows = 14
;block = 2
;eff = (mnl,d)
;alg = mfederov(candidates = explicit_profile3.csv)
;reject:
progA.yol=3 and progA.qol=6,
progB.yol=3 and progB.qol=6
;model:
U(progA) =
+ byol[0.000001] * yol[0,0.5,1,3]
+ bqol[0.000001] * qol[2,4,6]
+ bexp.dummy[0.000001|0.000002] * exp[0,1,2]
+ bsize[0.000001] * size[50,5000,10000]
+ bequ[0.000001] * equ[25,50,75]
+ bcost[-0.000001] * cost[20,40,60]
/
U(progB) = byol * yol
+ bqol * qol
+ bexp * exp
+ bsize * size
+ bequ * equ
+ bcost * cost
$

Despite adding the restrictions above, I'm getting a choice set in which progB.yol=3 and progB.qol=6 ... is that normal? or do I have a mistake in my syntax?

Many thanks!

Best wishes,

Pamela.

No that should not happen. Perhaps there is a mistake in your candidate set, please make sure that your columns have this format:

designr | choicetasknr | progA.yol | progA.qol | progA.exp | progA.size | progA.equ | progA.cost | progB.yol | progB.qol | progB.exp | progB.size | progB.equ | progB.cost

If you cannot solve the issue, please send me the candidate set by email. I will send you a private message.
