I have a dependent variable which status you close in (its a dummy variable). My predictor is how many months of experience counselors associated with the case has. There are about 11,5000 cases but only about 400 distinct counselors - they have many cases. So you have one number of the dv but the number of distinct predictors varies a lot from that (is much smaller). Does the linear regression assume the predictors are independent of each other in this case (I am not sure if the assumption of independence applies in this fashion or not). This is a really basic question, but I never thought about it before. 
I guess I am saying do you have to run a different type of regression or interpret the results different this way. I was going to look on line but I could not even think what topic covers this.
