I ran a LPA to explore the latent classes of risk factors of child depression. LPA result indicated a five class solution. However, when I try to look at the characters of each class, I encountered a difficulty. Results showed ODEL RESULTS
I am very confused about this result because none of my class indicator variables contains negative value. Thus, it is very confusing that the estimate of means of those variables are negative. Could anyone tell me what is going on? In addition, I noticed that the results also provide "STANDARDIZED MODEL RESULTS" which also contains negative values. Should I report the standardized results or not? Thanks very much!
Hi Dr. Muthen, I am running into a similar problem. I am using counts as the indicator variables in an LPA, and results indicated a 3-class solution. However, when I look at the mean estimates for each class, many are negative, and I'm not sure how to interpret them, as none of the indicator variables are below 0. Can you explain this? In addition, I have one variable where the mean estimate was approaching an extreme value and was set at -15. From what I've read on previous threads, this indicates that this indicator variable is 0 for this class with a probability of 1. Is that correct? Thank you for your help!
