LCA Minimum Number
Latent Variable Mixture Modeling
posted on Monday, April 07, 2014 - 5:24 pm
I was just wondering whether there is a minimum number of items which can be used within a LCA, or if the number of items can affect the number of classes?
Thank you in advance.

The number of items is not an issue. It is the items themselves. You may get different classes with different items but the classes will not be affected by the number of items alone.
There is a minimum number of categorical items that can be used for model identification. See Slide 72 of the Topic 5 course handout on the website.
