Hello: I am studying the effect of schools on student achievement growth over time. School effect is random. The effects of schools in prior years are assumed to be persistent till the current year. Thus, the total school effect in the second year is like J=J2+J1. Does anyone know how to model this kind of cumulating random effects in lmer? Thanks in advance!
