我的模型是4个变量,按理说应该给出6个约束条件,但是设置完了之后却出现The B matrix is fixed and the structural innovation variances are not estimated. Are you sure you want to proceed?请问高手这是什么原因?能留下联系方式最好,鄙人感激不尽!
同问 用文本输入
@e1=c(1)*@e2+c(2)*@e3+c(3)*@e4+@u1
@e2=c(4)*@e3+c(5)*@e4+@u2
@e3=c(6)*@e2+c(7)*@e4+@u4
@e4=c(8)*@e1+c(9)*@e2+c(10)*@e3+@u4
出来的也是这个The B matrix is fixed and the structural innovation variances are not estimated. Are you sure you want to proceed?
为什么呢?希望高手指点,谢谢喽~
