Here's the scenario. We have a years worth data on several school districts consisting of: � scores obtained from the beginning of the school year � scores obtained from the end of the school year � ordinal index of beginning of the school ability, e.g., at risk, mainstream, gifted � grade � demographic variables A student's score would determine group membership. We would like to use these data to predict the proportion of students in each group who will move from the current group (k) to the k+ith group. I'm thinking Poisson regression might be the way to go here. I'd like to hear/read others' thoughts. Thanks in advance.
