Dear Michael and other forum users,

Michael, following your advise few weeks ago, I managed to generate a design which looked great. I have just made some changes to the attributes and levels. Could you please check the syntax below for me. I will appreciate your feedback.

Design
;alts = A*, B*, C*, D*, None
;rows = 20
;block = 4, minsum
;eff = (mnl,d)
;alg = mfederov
;model:
U(A) = bscratching.dummy [0.120|0.130|0.140] * scratching [0,1,2,3] + bcages.dummy[-0.042]* cages[0,1]
+ bcert.dummy[0.15|0.16|0.17] * certification[0,1,2,3]
+ boutdoors.dummy[0.140] * outdoors[0,1] + bnesting&perches.dummy[ 0.133] * nesting&perches[0,1]
+ bprice[-0.47]* price[5,6,7,8](3-5,3-5,3-5,3-5)/
U(B) =bscratching.dummy * scratching+ bcages * cages + bcert * certification + boutdoors * outdoors +bnesting&perches.dummy * nesting&perches + bprice * price /
U(C) =bscratching.dummy * scratching + bcages * cages + bcert * certification + boutdoors * outdoors + bnesting&perches.dummy * nesting&perches + bprice * price /
U(D) =bscratching.dummy * scratching + bcages * cages + bcert * certification + boutdoors * outdoors + bnesting&perches.dummy * nesting&perches + bprice * price /
U(None) = b0[-3]
$

The syntax looks fine to me.
