因为有看到有人说:eviews估计状态空间模型,需要用不同的参数初始值做循环估计,不然得到的估计结果很可能是次优的
选择参数的初始值是靠经验吗?

初始值问题,似乎没有哪个软件能解决吧?
EViews 的好处,就是大部分模型,不需要用户设置初始值就能估计,他对特定问题,内建立初始值的算法程序,对用户是透明的
请问,那人这么说,有没有给出具体的建议?
我感觉,初始值问题,还是具体问题具体分析,有时候还要靠运气,呵呵

陈老师,今年有幸买到的您的那本厚重的讲义,我是一名初学者,学校开的这门课的老师只会泛泛而谈,没有讲明白一个模型,我是失望之极啊!前面看了几本参考书,看的是云里雾里的,全是理论,没有实例,害人啊。当时看到您讲义中序言写到十年的艰辛执着,学生很是敬佩啊,这样教授确实罕见了。我太想明白计量模型中的奥妙了,可是只能一个人一点点摸索了,看了一些书,走了不少弯路,至今还是失望,所以只好把您的讲义拿来研读挽救自己的兴趣了。这里我想问您一个简单的问题,请您不要生气啊,呵呵,讲义中的所有案例数据可以从网站上下得到吗,还是自己下论文获得。希望您指点一下吧。

本讨论组置顶的帖子的附件就是啊
如果您不能web访问,人大经济论坛也有人转过去了。我现在上不了人大论坛,不然就直接告诉您地址。

为了方便大家学习,陈老师已经将讲义中用到的数据上传了,见下帖,以及其他同学的讨论

如果您仔细读用心学,陈老师的书会帮你挽救自己的兴趣的,我相信。
