hi

I'll like to fit a model like

X_ij =3D a_i + e_ij
i=3D1...20
j=3D1,2,3

where a_i are iid normal whith mean=3D a and sd =3D sigma
and where e_ij are iid normal with mean =3D0 and sd=3Dw_j

i.e. different residual error on different days

I have tried with xtmixed, but I cant make it work

any hint?

please cc: korsholm@stat.sdu.dk
