I have read your document for the 3-step method in conducting an LTA. Whereby you first run all of your latent class models separately. You then run some calculations to get the values that you will include in the LTA to account for measurement error.
I am struggling to identify the formula you use. You mention a formula (1) but I cannot seem to find it listed anywhere.
