looking for to find the suitable model for Latent class mnl analysis

[Arsab buki]

Hi,

I have a dataset that contains four choice tasks for each individual, with five alternatives for each task and four different attributes. Additionally, I have four other variables that are constant for each person (gender, income, age, area). As shown below, part of my dataset is displayed.
I am seeking a Latent Class MNL model with a reference category (alternative B). In addition to the table comparing the coefficients for each alternative, I need to know which class each person belongs to. I would appreciate your advice.

ID	Choicetask	Alternative	Choice	Attribute 1	Attribute 2	Attribute 3	Attribute 4	Female	Age	Income	Area
