In most biometric applications, those variances are treated as nuisance parameters. They only need to be controlled for, while the main purpose is to get the right point estimates and standard errors for the fixed effects. In social science multilevel modeling (of which education is probably the he

Dear experts, I use R to conduct multilevel modeling. However, I have a problem about the interpretation of random effect. Unlike the variables in fixed effects, the variables in random effects have not shown the standard error (s.e.) and p-value, so I don't know whether the
