Dear Michiel,

Thank you for the quick response, this will give me a starting point. I appreciate your continued help.

Thanks

Harold.

Dear Michiel,

Sorry I made a mistake in my previous post. The question is supposed to read as follows;

- What is the limit to the number of variables you would have in Nlogit?

Dear Michiel,

As a novice with choice experiments, I have been learning how to prepare and analyse data using Nlogit. After reading Hensher's book, I have gained some ideas though I still need your guidance. I just did a test run with my survey and obtained a few responses. My design from Ngene is ...

Dear Michiel,

Thank you very much for the response, this will help.

Dear Michiel,

Thank you for guiding me so far on how to go about generating choice sets using Ngene. Your responses have indeed enhanced my understanding of choice experiments. The last time I posted a question, I forgot to mention I intend to use Latent Class Model to analyse data. I have realised ...

Dear Michiel,

Thank you for the quick response. I will go through the constraints again, I may have missed something.

Hi Michiel,

The levels for the attributes are as follows:

1. Nestingperches&scratching = (1) Present and (0) Absent

2. Production = (1) Battery cages, (0) Colony cages, (2) Barn and (3) Free range

3. Mortality = (3) High, (2) Medium, (0) Low and (1)Very low

Note: The numbers in brackets are ...

Hi Michiel,

I made some changes from the last time I posted some questions; I changed my syntax to relax some level combinations. However, it seems like I'm still struggling to have a breakthrough on this. Please guide me on any other method to avoid contradictions in attribute combinations/levels ...

Dear Michiel,

Thank you for your usual quick response. I appreciate it. I'm learning a lot from this forum.

Hi Michiel,

I changed some attributes and levels for the design. I redefined the attribute, 'cages', and its levels: 1 = battery caged (-0.126) , 2 = cage free (0.54) and 0 = colony caged (0) as a base. The results I got are as follows:

- D. error = 0.4778
- S. estimates = 224.14

1. Is the D ...
