I'm new to the STATA software. But been following tutorials. I need to perform a choice based conjoint analysis to my research study. There was a previous research study performed using conditional (Fixed effect) logistic regression below link
https://repository.library.georgetow...pdf;sequence=1
In this thesis. The 16 alternatives were randomly ordered to create eight pairs of alternatives. A total of 8 choice sets were selected for estimation. Because only the differences in attributes levels matter in logit models, The respondent would be presented with three alternatives, two alternatives refer to different product profiles and the third option refers to an opt-out alternative, which states “I would not buy either product to the left”. These 8 choice sets were randomly assigned into two versions. Each version has four choice sets for estimation and one additional for validation.
Every respondent received either one of the two versions. The response variable, whether or not an alternative is chosen is coded with 1 when chosen, and 0 otherwise. There are three alternatives for each choice task. For each of the product attributes categories, one of the attributes levels is omitted and the others are assigned a value of 1 if chosen, and 0 otherwise.
An alternative-specific constant (ASC) “c” was created to represent the “neither option” (option C). This was coded as 1 if the respondents choose the “neither” alternative, and 0 if they
choose one of the product alternatives. I don't know how to apply this to my research to calculate part worth utilities, please help. If you can send a screen shot of applying the data in data editor. It will be a great help.
