Hi all,
I haven't found a suitable post in the forum, therefore my direct question:
What would you recommend as sample size if I apply repeated measures, i.e. a longitudinal study? I have three points in time, at which I applied the same questionnaire and established the same model. Do I have to treat all indicators and LV relationships as independent and therefore multiply the minimum sample size of the simple model by 3, or would you recommend the sample size from a simple, viz. one-time model?
thanks in advance,
matthias
