Using some statistical techniques, such as linear regression is no longer
valid, due to you not having independent observations (within individual)
....What about linear regression based on scores of pre and post
observations in a single individual? I also ran multiple regression on data from single
players, looking at how varying HRV on each measurement occasion (prior to
every at-bat) and it's effect on outcome (each at bat's result)? I then
compared pre and post with intervention differences in how HRV predicted
performance. This was done on every player in the line-up for the entire season (over
140 measurement occasions pre and post).
