    Congratulations, another well done video. I enjoyed most of it, but I had to re-run the sections about different movements several times as the material seemed to come hot and heavy.

    I have a comment about the clinical application of the mixture model. M. Rohlings et al. make the point that for populations with low base-rates to exist they would have to share an underlying variable with an Effect Size of 20.0 whereas most meta-analyses rarely reveal psychological variables with E.S. over 2.0.

    I look forward to the next video,
