[R] mixed effects regression with non-independent data

Hi, I will be performing mixed effects regression on subjects total scores from 2 player games (prisoners dilemma) that played. I am aware that including both players score from a game will cause problems due to non-independence. Is there a way that to deal with this apart from randomly picking

[R] Mixed models with missing data

Hi, I am creating a mixed model based on a experiment where each subject has 2 repeats. In some instances though there is only data for one of a given subjects repeats for most there is data for both. Can I still justify having subject as a random effect? Thanks, Jonathan [X] [X] [X] [X]
