请大家帮我看一下我下面的运行结果好吗？1.这里面哪些代表的是[img]file:///C:\Users\qiuyu\AppData\Roaming\Tencent\Users\397577109\QQ\WinTemp\RichOle\8W8@[IT~RKQC$6$GG{4BP}X.jpg[/img] 呢？2.那结果中的 sigma-squared是哪个的呢？3.哪个才是beta分别的值呢？4.the likelihood value is less than that obtained using ols! - try again using different starting values    出现这句话的时候我该怎么调整数据呢》希望有好心人可以解答我的问题，感激不尽！！！！！！！


the final mle estimates are :

  beta 4         0.12105655E+00  0.79235754E-01  0.15278021E+01
  sigma-squared  0.37041226E+00  0.88254700E-01  0.41970826E+01

  eta            0.00000000E+00  0.10000000E+01  0.00000000E+00

log likelihood function =  -0.28587513E+02

the likelihood value is less than that obtained
using ols! - try again using different starting values
