 Hi r-sig group
I want to know how to write the code of simulating a linear random intercept model with following assumptions using R programing:
the model:
yij=b.+b1 xij + u.j + eij,  where j refer to the group number and i refer to the observation number in the j group
model assumptions:
  1- xij ~ N (3,1.5)  2- u.j ~ N (0,1)  3 - eij ~ N (0,1)  4 - cov (xij , u.j)=0  5 - cov (xij , eij)=0
  6- cov (u.j , eij)= 0
thnx for help
