partial clustering at an intermediate level
Posted: Wed Aug 20, 2014 8:40 am
Hi,
I am running a logistic multilevel model with approximately 200,000 individuals nested in 50 states. My interest is in the state level coefficients as contextual explanatory variables. A complicating factor is that 23% of the cases are individuals that are further clustered by household (usually two people per household, but occasionally 3 or 4 per household).
If I run a 3 level empty model with MQL1 (won’t converge with PQL2) the residual household variance is 0.027(0.106) state residual variance is 0.031 (0.009). If I run MCMC residual household variance is 0.0 (0.0) and the state residual variance is 0.032 (0.009).
I haven't been able to find any literature relevant to this situation. Is it reasonable to run this as a two level model with just individuals nested within states?
Many thanks in advance
