Without a detailed description of the data and the assumed correct dgp
from the original poster, it will be hard for anyone to comment
usefully on the estimation problem.
It strikes me as strange to model RE in one dimension and clustering
of errors in another; two-dimensional clustering or a multilevel model
seems a more natural starting point.

With some examination through Statalist, I realised that my panels (individuals) are not in the same cluster (household) all the time (because individuals move in and out of households over time). Then, I've found that 'nonest' option somehow helps not receiving the same error. Though I wanted to find out more about this option, the information online seems limited. So, I'd like to ask you (1) what 'nonest' option does and (2) whether it is a right cure in my case.
