Dear Ngene experts,
This question relates to a general question: in Ngene, how should be handled the case of two alternatives including the no-choice option, i.e. a simple choice of "take it or leave it".
More specifically, I am designing a D-efficient bayesian choice experiment with two alternatives including a no-choice option. The respondents will be facing 4 choice tasks under which they are asked whether they will be offering a contract under the circumstances determined by the dummy-coded variables market, regul and measures. Their answer is in the form of a 4-likert scale: yes, rather yes, rather no, no.
I want to launch a pilot using the following code in order to estimate some priors (set to zero now because I have no information on the effects: nor in sign or magnitude).
Design
;alts=alt1, alt2
;rows=24
;block=6
;eff=(mnl,d)
;model:
U(alt1)=b1.dummy[0|0]*Market[0,1,2]+b2.dummy[0|0]*Regul[0,1,2]+b3.dummy[0|0]*Measures[0,1,2] $
Nevertheless, I thought that the appropriate way to estimate this model in order to compute the priors may be to used random effects or fixed effects ordered probit or logit rather than MNL. Therefore I have the following questions:
1) Is there a way to model panel ordered probit/logit in Ngene?
2) Would you suggest me to estimate the priors using another method existing in Ngene?
Thanks a lot in advance for your precious help.
Best regards.
