I'm having trouble trying to get rid of something that has come up in my output, underneath intercept. I'm not sure what I entered to get it there. I have attached a picture of the outputs with/without.
I wonder if anyone can help me. I am trying to do a multivariate linear regression, I have 3 dependent variables with 2 separate time points for each, how do I condense this into three variables so that I can look at the time points together.
