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 mervat [[alternative HTML version deleted]] _______________________________________________ R-sig-mixed-models@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-sig-mixed-models
