大家好，我在做dairy研究，现在想探究中介效应，采用1-1-1的语句（参考preacher的input），但是output里没有卡方，标准化的结果，也没有r-square，并且出现这样的提示

（不过结果里中介效应是显著的）

。请大家给点意见！！！
*** WARNING in OUTPUT command
  STANDARDIZED (STD, STDY, STDYX) options for TYPE=RANDOM require ALGORITHM=INTEGRATION.
  Request for STANDARDIZED (STD, STDY, STDYX) is ignored.
   1 WARNING(S) FOUND IN THE INPUT INSTRUCTIONS

THE MODEL ESTIMATION TERMINATED NORMALLY（

模型估计正常终止）

     A MATRIX COULD NOT BE INVERTED DURING THE H1 MODEL ESTIMATION.
     THE ESTIMATED BETWEEN COVARIANCE MATRIX IS NOT POSITIVE DEFINITE AS IT
     SHOULD BE.  COMPUTATION COULD NOT BE COMPLETED.
     THE VARIANCE OF C_SS APPROACHES 0.  FIX THIS VARIANCE AND THE
     CORRESPONDING COVARIANCES TO 0, DECREASE THE MINIMUM VARIANCE, OR
     SPECIFY THE VARIABLE AS A WITHIN VARIABLE.
     THE H1 MODEL ESTIMATION DID NOT CONVERGE.  CHI-SQUARE TEST AND SAMPLE STATISTICS COULD NOT
     BE COMPUTED.

编码主要内容如下：

%WITHIN%
    sa | c_SS on c_gr;
    sbP | PA on c_SS;
    scP | PA on c_gr;

    sa sbP scP c_gr c_SS PA;
    sa with scP c_gr c_SS PA;
    sa with sbP(cabP);
    sbP with scP c_gr c_SS PA;
    scP with c_gr c_SS PA;
    c_SS on c_gr(ab);
  !remember that the path from c_gr to c_SS was SHARED
    PA on c_SS(bbP);
    PA on c_gr;
    [sa](aw);
    [sbP](bwP);

    model constraint:
    new(a);

    bP=bwP+bbP;
    indwP=aw*bwP+cabP;
    indbP=a*bP;
