I have a couple of questions that I cannot seem to find the answer to.
For binary and categorical variables to be used in SEM, do they need to be in a particular order for Mplus?
Question 1 - My categorical variables are not measured on a likert scale but say I have a variable that assesses education (1: primary school, 2: high school, 3: university). If I want to include it as an indicator of latent variable "socioeconomic status." does it matter what order the variables are in? Presumably, university then becomes a measure or a high socioeconomic status? And if the order was to be reversed then primary school becomes is measure of low socioeconomic status? Am I correct in assuming this is what Mplus will assume if we ask those questions?
Question 2 - Do categorical variable need to be in 1,2,3,4 etc order or do they need to be 0,1,2,3 etc?
Question 3 - And is that also they case for binary (0: no education, 1: high education) or (0: high eduction, 1: no education). Or does the order not matter?
