Hello,
I have a problem with writing a suitable code for the "cmset" command in STATA 16.
We have a dataset from the discrete choice experiment (DCE) with 18 choice sets/cards. On each choice card, there were 2 alternatives (with 5 attributes) and an opt-out ("status quo") option (variable alt). Each respondent (variable id) was allocated to one of the blocs (variable bloc) with 6 choice cards (variable card).
Could you please help with any ideas on how to correctly write this command?
Thank you in advance,
Tanja
"cmset id alt" should set your data in the Stata required format
Start with the following syntax using Stata as Alvaro mentioned above
cmset id alt
Now, your data in Stata is ready for summarizing data and implementing district choice models. For example, for data summary use the following syntax;
cmssummarize
For example, for conditional logit model,
cmsclogit
Also, refer to Stata 16 Manual. The above syntaxes are clearly discussed.
I hope this helps.
Regards
Dear Tanja, I am looking for an answer to the question you asked: how to cmset a dataset based on DCE. In my case repondents were allocated to two blocks with 8 choicecards, each including two alternatives. I have read the STATA manual, and the responses above, but do not find answers to how to CMSET these data. Did you find a solution to your question that can guide me?
I used command cmset id alt, but it gives me the error:
at least one choice set has more than one instance of the same alternative
r(459);
does anyone know I should i deal with this problem?
