    Coefficient of Multiple Determination/Correlation (CMD/CMC) Troubleshooting

    Hello Biomechanists,

    I am trying to calculate coefficient of multiple determination (CMD) and correlation (CMC) but I keep getting negative numbers when values should fall between 0 and 1. I have based my calculations off of the original Kadaba 1989 article (attached) and it seems to me my code follows the equations provided in the article, however I still get some negative numbers for CMD. Does anyone have experience with CMD and CMC calculations? I am happy to provide sample data and code.
