Dear all
I hope you can help me. I just started working with this amazing software (thanks professors Bliemer, Rose, Collins and team). I have three questions:
1. If I write * to avoid dominant alternatives (alt1* and alt2*) do I also have to use the * in the SQ alternative?
2. Ngene has been running for an hour and the last 40 mins has been stuck in the last iteration. Can I just double click that row and choose that exercise or I need to wait till the software stops completely?
3. If the answer to 2 is that I can just choose that last row (even when the software is still "running") I wonder why in the resulting design my "require" specifications for the "SQ" are not respected by the software (there are some choice tasks that have tax=0 or tax=2 even when I specified a required sq.tax=1). This is my code:
Design
;alts = alt1*, alt2*, sq
;rows = 18
;block = 3
;eff = (mnl,d)
;con
;cond:
if(alt1.tax <> alt2.tax, alt2.fee <> alt1.fee or alt2.fee = alt1.fee) ,
if(sq.tax <> alt2.tax, alt2.fee <> sq.fee or alt2.fee = sq.fee) ,
if(sq.tax <> alt1.tax, alt1.fee <> sq.fee or alt1.fee = sq.fee)
;require:
sq.vis = 1 and sq.colpre = 1 and sq.fee = 1 and sq.tax = 1
;model:
U(alt1) = A1[0.001]*vis[0,1,2] + A2[0.001]*colpre[0,1,2] + A3[-0.001]*fee [0,1,2] + A4[-0.001]*tax[0,1,2]/
U(alt2) = A1*vis + A2*colpre + A3*fee + A4*tax /
U(sq) = A1*vis + A2*colpre + A3*fee + A4*tax + A5[0.01]

Many thanks friends
