mplus结果显示THE MODEL ESTIMATION TERMINATED NORMALLY
     THE STANDARD ERRORS OF THE MODEL PARAMETER ESTIMATES COULD NOT BE
     COMPUTED.  THE MODEL MAY NOT BE IDENTIFIED.  CHECK YOUR MODEL.
     PROBLEM INVOLVING THE FOLLOWING PARAMETER:
     Parameter 53, GJ WITH ZZ
     THE CONDITION NUMBER IS      -0.188D-08.
语法如下：
USEVARIABLES are mr1-mr3 fr1-fr3 s1-s3 IGD1-IGD3 g1-g3;
    ANALYSIS: ESTIMATOR=ML;
    MODEL:
    qz BY mr1-mr3 fr1-fr3*;
    IGD BY IGD1-IGD3*;
    zz BY s1-s3*;
    gj BY g1-g3*;
    OUTPUT: STANDARDIZED;
            MODINDICES;

mplus官网上给的解释是The number of clusters is the number of independent observations in your data set. The warning is telling you that you have more parameters than you have independent observations. The impact of this on the results has not been studied. This is simply a warning.（

群集的数量是数据集中独立观察的数量。警告告诉你，你有比独立观察更多的参数。这种情况对结果的影响尚未研究。这只是一个警告。）请问该怎么解决呢
