LISREL的输出结果中,外源变量指向内生变量的线值大于1或负值是怎么回事?

请高手指教以下问题:<br /> &nbsp; &nbsp; 1.LISREL的输出结果中,外源变量指向内生变量的线值大于1或负值是怎么回事?<br /> <br /> &nbsp; &nbsp; 2.在检验全模型或中介模型的时候,一直出现“W_A_R_N_I_N_G: PSI is not positive definite”<br /> &nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;或“W_A_R_N_I_N_G: The solution was found non-admissible after&nbsp;&nbsp;50 iterations.<br /> &nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; The following solution is preliminary and is provided only<br /> &nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; for the purpose of tracing the source of the problem.<br /> &nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; Setting AD&gt; 50 or AD=OFF may solve the problem<br /> <br /> 不知道是哪里出了问题。。。。。。<br /> <br /> 我的程序如下:<br /> DA NI=15 NO=98 <br /> KM SY <br /> (相关矩阵)<br /> MO NY=10 NX=5 NE=2 NK=1 PH=SY,FR TD=DI,FR TE=DI,FR PS=SY,FI BE=FU,FI<br /> FR LY 2 1 LY 3 1 LY 4 1 LY 5 1 LY 6 1 LY 8 2 LY 9 2 LY 10 2 LX 2 1 LX 3 1 LX 4 1 LX 5 1 GA 1 1 GA 2 1 BE 1 2 BE 2 1 PS 1 1 PS 2 2<br /> FI LY 1 1 LY 7 2 LX 1 1&nbsp;&nbsp;<br /> VA 1 LY 1 1 LY 7 2&nbsp;&nbsp;LX 1 1 <br /> PATH DIAGRAM<br /> OU SS SC MI

<strong> 1# <i>load34</i> </strong> <br /> <br /> 你的问题是参数设置不当<br /> 这类问题我见过很多:标准化以后系数绝对值大于1<br /> 具体联系 QQ: 99847730
