Hello there,

Thank you to anyone who takes the time to read this. To make a long story short, I’ve got a dataset with 58 participants each of whom have completed 4 testing sessions. What I’d like to do is assess the IV’s that contribute to within person fluctuations in a measure between sessions. I believed MELS would be appropriate but it’s more suited to richer datasets and the model converges with unreliable estimates. I’d like to preserve the longitudinal structure of dataset so collapsing into a single value isn’t ideal, but I’m struggling to find a solution to this issue.

Any resources/assistance is truly appreciated and I thank anyone who took the time out of their day to help!
