Hi Amanda it really depends what your goal is. If you want to estimate the noise for a power analysis and you are going to process the data longitudinally, then certainly you should use the longitudinal stream to measure the reliability cheers Bruce On Wed, 20 Sep 2017, Worker, Amanda wrot

Hi all, I have a longitudinal dataset that I'd like to calculate test-retest reliability for. However, I am not sure whether to calculate this for the cross-sectionally processed data or longitudinal data? It would seem to make sense to use the cross-sectional data, as the time points are inde
