    HELP: Linear mixed models

    In my analysis I am trying to predict how ratings of cuteness of dogs (5 dogs) predict the levels of depression for each subject. Depression ~ Cuteness ratings Now for each subject, there are 5 ratings (Cuteness), but only one depression score. Can I run this analysis with the single depression...
