WARNING:  THE LATENT VARIABLE COVARIANCE MATRIX (PSI) IS NOT POSITIVE
     DEFINITE.  THIS COULD INDICATE A NEGATIVE VARIANCE/RESIDUAL VARIANCE FOR A
     LATENT VARIABLE, A CORRELATION GREATER OR EQUAL TO ONE BETWEEN TWO LATENT
     VARIABLES, OR A LINEAR DEPENDENCY AMONG MORE THAN TWO LATENT VARIABLES.
     CHECK THE TECH4 OUTPUT FOR MORE INFORMATION.
     PROBLEM INVOLVING VARIABLE L.




     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 49, V
以上是提示错误的语句。
以下是我的命令语句：
usevariable= t1-t10 sl1-sl4 pp1-pp4 ip int1-int4;
   define:center t1-t10 sl1-sl4 pp1-pp4(grandmean);
          int1=sl2*pp4;
          int2=sl3*pp3;
          int3=sl1*pp2;
          int4=sl4*pp1;
  analysis:estimator=ml;
           model=nomeanstructure;
           information=expected;
  MODEL:l by t1-t5*;
        v by t6-t10*;
        t by l v;
        sl by sl1-sl4*;
