按照温忠麟老师的文章用潜调节结构方程（LMS)进行有调节的中介效应分析，在运行Mplus时得到以下结果:<br>
     THE MODEL ESTIMATION DID NOT TERMINATE NORMALLY DUE TO A NON-ZERO<br>
     DERIVATIVE OF THE OBSERVED-DATA LOGLIKELIHOOD.
     THE MCONVERGENCE CRITERION OF THE EM ALGORITHM IS NOT FULFILLED.<br>
     CHECK YOUR STARTING VALUES OR INCREASE THE NUMBER OF MITERATIONS.<br>
     ESTIMATES CANNOT BE TRUSTED.  THE LOGLIKELIHOOD DERIVATIVE<br>
     FOR THE FOLLOWING PARAMETER IS -0.58759244D-02:<br>
     Parameter 4, [ X4 ]<br>
请问这个是模型不合适的意思吗？我该怎么调整呢？
