When you say panel data, I interpret that as each subject being measured at more than one time point. The analysis depends on whether or not you want to model the development over time, or simply take into account the across-time correlations for each subject. In the former case you do longitudinal modeling such as growth modeling.
Hello, I am trying to run a panel analysis using two waves of longitudinal data. MPlus is installed on my Macbook computer. However, MPlus does not run the analysis (or at least it does not show the usual "working" window I expect when running a complex analysis). Instead, it opens a completely blank output window. Is this an issue with the syntax I am using, or a software problem? Thank you so much for your help! Kathleen
