Dear prof Michiel and others,
I have run the following design. I wonder why am I getting too many extreme values in my prices?, for example the price of 228 is supposed to be the choke price which many people are not expected to choose but it appears many times.
Can you please lend me a hand?

Design
;alts = alt1*, alt2*, sq
;rows = 12
;eff = (mnl,d,mean)
; alg = mfederov(stop = total(10000000 iterations))
;require:
sq.PRDUR = 1, sq.ALOM = 0, sq.IRGM = 0, sq.POLUNCER = 0 , sq.WTRPRI = 38
;bdraws = gauss(1)
;model:
U(alt1) = b2[(n,0.209265,0.0086001)] * PRDUR[2,5,1] + b3 .dummy[(n,0.199165,0.0108026)] * ALOM[1,0] +

b4 .dummy [(n,-0.361222,0.007969)]* IRGM[1,0] + b5 .dummy [(n,0.395512527,0.01824397)|(n, 0.476775789,0.02880091)] * POLUNCER[1,2,0] +

b6[(n,-0.0018, 0.0038606)] * WTRPRI[20,38,76,114,152,228] /

U(alt2) = b2 * PRDUR +

b3 * ALOM +

b4 * IRGM +

b5 * POLUNCER +

b6 * WTRPRI /

U(sq) = b7[0] +

b2 * PRDUR +

b3 * ALOM +

b4 * IRGM +

b5 * POLUNCER +

b6 * WTRPRI

I already this question in your previous post: http://choice-metrics.com/forum/viewtopic.php?f=4&t=481&start=10
Note that all questions related Ngene and syntax should be posted in the Ngene forum.
