Thanks, that 10% response rate is also correct for colleagues, what to do? . However, since most of them pay same toll and zero parking fee, we were afraid all the answers would be very similar. I am thinking of having few designs and some of attributes only included in one design and not rest ...

Thank you Michiel,

You cant believe how data collection for choice experiment is difficult here. Response rate is almost only 10% and the time I was doing pretest I wasn't very sure whether respondents really trade off. This pretest took almost 3 months for us. But since I myself collected the data ...

Thank you so much Michiel, I am trying it as well. Unfortunately I keep getting errors. The results of short model from pretest wasn't that good. One more thing, in our pretest, TVC (car travel time) is pivoted around current reported travel time, and TVT and TVB pivoted around TVC. All attributes ...

Hi Michiel,
Many thanks. Design is as follow. I put the priors (significant and correct one) from pretest (obtained from MNL model), (n, mean, standard error) for less insignificant but correct signs, and for those variables which are very insignificant or having wrong sign I put (u,-1, 0) in the ...

Dear Ngeners,

I have been facing with problem with Ngene since yesterday. It keep hanging almost 2 out of every 5 times I click to see output window.

Second problem is with huge S estimate, however, I put the priors (significant and correct one) from pretest and ((u,-1,0) for insignificant or ...

Dear Michiel,

First of all many thanks to you and all Ngene team for kind help, guide and patience. It s really great to know you guys are there to help and we can count on it. As suggested earlier, I m using MNL design for pretest, using near zero priors. I am using actual levels as it is easier ...

Hi Michiel,

Thank you. The confusing part was segment which I think I am clear about it now.

Hi dear Ngene team,

I am trying to do a pivot design related to mode shift in Kuala Lumpur. We have 3 alternatives (drive alone, train and bus) and each with related attributes and levels. After reading Manual and some other papers from Ngene team, I ‘m still little (honestly more than little ...

Thanks Michiel,
That 20 was after eliminating some attributes and declining number of levels. Many thanks! so I am free of orthogonal design now. such a relief!

Hi every one,

Actually I have small question on orthogonal design:
I want to use efficient design but since I have no information on priors I have to have some small pretest using orthogonal design. I know more levels lead to more complicated choice task and big number of scenarios. I have 3 ...
