dummy variables with interaction
Dear Ngene team,
I have done a D-efficient design using Ngene for my study using dummy var with zero priors and interaction as below:
;alts = alt1, alt2
;rows = 240
;eff = (mnl,d)
;block = 20
;model:
U(alt1)=
b1[0] * DUR[1,3,5,7,10](38-58,38-58,38-58,38-58,38-58) +
b2.dummy[0|0|0|0] * Prt[1,2,3,4 ...
