Hello,
I am planning to conduct an LCA and LTA using a mix of binary, categorical, and continuous indicators. Do you have any recommendations regarding resources for how to specify the input, as well as how to interpret the output?
Thank you in advance.

See UG ex7.11 for syntax. The interpretation is in line with regression analysis with those types of outcomes. We describe such regressions in Topic 2 as well as some more in Topics 5 and 6 of our video-taped short courses from Baltimore and Berlin. I can't point to application papers I'm afraid - others?

Hello, thank you for your response. I will look at those resources. Related to entering binary data, do the response options have to be 0's and 1's, or can they be 1's and 2's? Or can the response options for some of the variables be 0's and 1's while the response options for other variables be 1's and 2's?

Thank you again.

They can be 0/1 or 1/2 or a combination. They are change to 0/1 before analysis.

Hello, thank you for your response. So they need to be changed to 0/1 before analysis, correct?

You don't have to make any change to your data. The program changes to 0/1 internally.

Ah, thank you!

Sorry, one more question -- I am assuming that in the "results in probability scale" output, category 1 represents the 0's and category 2 represents the 1's, right?
Thank you again.

Right.
