Dear all THE FOLLOWING did not include the intercept (constant) therefore, is the following acceptable to run the efficient design ..tq
Design
;alts = alt1*, alt2*
;rows = 12
;eff = (mnl,d)
;block = 2
;model:
U(alt1) = b1[0.17]*A[0, 1, 2] + b2[0.18]*B[0,1,2] + b3[0.13]*C[0,1,2] + b4[0.13]*D[0,1,2] + b5[-0.2]*E[0,1,2,3] /
U(alt2) = b1*A + b2*B + b3*C + b4*D + b5*E$
