    Correlation based on multiple measures / observations

    Hello everyone! I am hoping someone could offer me some wisdom and a few R tricks. I was lucky enough to get a pretty interesting data set for a study that I am doing. There is approximately 5000+ rows of data spanning 5 years for 100 different sales people. The data is structured per...

    repeated measures, 3 conditions and multiple DV's in each of the conditions

    Our experiment design is kind of complex: 35 participants, stimuli were approaching cones that disappeared at different distances (conditions: near (20 cm), mid (60 cm) and far (120 cm). The cones were seen through the oculus rift. Participants estimated the distance where the cones...
