I have data on every grade in all elementary schools in Chicago over 5 years. I
would like to estimate a trend over time for each grade in each school. There
are 17,600 data all together (about 460 schools, nearly 8 grades each, over 5
years). Is there a not-so-hard way to do this in R (I was thinking of using
rlm)?
