我想要在mplus 测试两个一级变量的interaction 总是显示TYPE=TWOLEVEL requires specification for the CLUSTER option 可是我已经输入了cluster=学校编码了
USEVAR = Schoolnr TB CSE c_mccur_LKR c_Minority_birth_klasmean
Reken_toets_klasmean SES_klasmean interC;
DEFINE: interC = c_Minority_birth_klasmean * c_mccur_LKR;
WITHIN = TB CSE c_mccur_LKR c_Minority_birth_klasmean
Reken_toets_klasmean SES_klasmean interC;
CLUSTER = Schoolnr;
ANALYSIS:
TYPE = TWOLEVEL;
MODEL:
%WITHIN%
TB ON c_mccur_LKR c_Minority_birth_klasmean
Reken_toets_klasmean SES_klasmean interC;
CSE ON c_mccur_LKR c_Minority_birth_klasmean
Reken_toets_klasmean SES_klasmean interC;
c_mccur_LKR c_Minority_birth_klasmean Reken_toets_klasmean SES_klasmean interC;
%BETWEEN%
