    最近两个小发现

    1. 盗版的stata 10不如盗版的stata 9好。每次跑个简单的程序，stata10 给出的结果都不一样，太让我心凉了，要是弄个regression结果怎么让我信任。装了10是因为据说可以做GMM，现在连个简单summary我都不敢信了。
    2. 来UMN快一年了，竟然没人告诉Patrick Kehoe和Timothy Kehoe是兄弟俩。我早前就觉得这两个长的像，而且连middle initial都一样。今天查wiki才发现，前者是后者的弟弟。但前者更出名，连他的RA学生今年都去了wharton finance当老师。不过他们俩不怎么co-work，虽然是兄弟而且就隔着一个办公室。

    to 古月：你们真好，用正版，我们这matlab，stata，sas等均需自己提供，不过Windows是学校提供正版的，哈哈。。。。
    新版增强了很多功能，比如Arellano-Bond Regression之类

    Guyue Xuwrote:
    haha, 你也用这个，我先前用的D版的Stata9，后来老师给了正版的Stata10，觉得没有什么不一样呀。
    不过，我大多数情况下run的是regression

    to laigangbin：呵呵，我可不牛，R是不错，不过我太懒，stata有很多build in的regression，比较省事

    呵呵，进来景仰一下大牛……
    自我感觉还是R爽……也没盗版一说了……

    我用stata 10.1的盗版用得挺好的啊，不过我是用mac的，不是PC
    by the way，stata的help file实在是太不helpful了！昨晚在编simulation的程序，发觉要在stata里generate一个50*1的column vector，里面全是1，命令居然是J(50,1,1) ¥@¥％＃％＃！，而且我在help里还找不到这个，我是google出来的，wtf！

    Patrick确实厉害，economist按publication, citation之类的ranking都是有他没有他哥哥，他当年在Harvard读PhD但是其实是Sargent的学生每年夏天都来Minnesota
