based on the data of a CBC I would like to perform a latent class analysis. In the CBC a Dual-Response None question was implemented, asking the respondents if they would switch from their current contract to the selected one. This allows us to look at the willingness of respondents to switch. I did several runs with and without the dual none as a parameter in the estimation. The segments are similar to some extent in their preferences, but there are still differences, for example in the segment sizes.

Is it better to perform the estimation of the preferences using only the product attributes and their levels or should I consider the Dual-Response None as a parameter?

How much does the integration of the "Dual-Response None" influence the estimation of the preferences?

Thank you!

You are right that i would like to detect market segments for strategic segmentation purposes. So I understand that it is hard to choose between the options.

The CBC consisted of 8 choice tasks with 3 concepts each. There were 4 attributes with 2, 3, 4 and 4 levels. The adjusted data set consists of 777 participants.

In the latent class analysis, for the 4 segment solution, I get approximately the following values for the Dual-None Response parameter:

Raw Utilities: -0.85/ 3.13/ 0.50 and 5.07.

Zero-centered diffs: -50.71/ 215, 03/ 39.13 and 310.78

How would you interpret the influence of these values?

Thanks!
