再转一页, 夜深人静的时候,想想,是别人的问题,还是自己的问题。

一直在思考,从未想明白,一直在围观,从未有真相。精典!

智利总统要帮助中国战胜矿难,解救矿工!

作者:李寻欢1990 回复日期:2010-10-17 15:15:33

当局做事从来不讲信价比,成本太高,虽说都是屁民的钱,但来回的折腾你们不累?
要说信价比,智利的大营救的政治收益要比你们搞十个奥运会,八个世博会还要高。

又死了几十个矿工,感谢国家,感谢政府。

难怪现在石油上窜下跳。如果你的心脏好UWTI日交良品。

随着油价腰斩,美国油企的日子过得非常辛苦,雪上加霜的是债市也把能源企业相关的
债券扫地出门了。
上周末,因贷款人拒绝提供更多资金,石油公司WBH Energy申请破产保护,而今天据彭
博社的报道,美国油企Resolute Energy与Highbridge资本管理公司达成一项条约,保
证对来自于后者的1.42亿美元贷款偿付至少25%的利息。此外,Linn Energy为获取黑石
集团(Blackstone)5亿美元的贷款,承诺付出部分油井85%的开采权益。
由下图可以看到,Resolute Energy公司5年期债券价格不到半年来遭到腰斩,收益率大
概在27%至32%之间:

The Most Indebted US Oil Companies
By Shobhit Seth | February 23, 2015
The effects of declining oil prices over the last few quarters have started
to show. January 2015 saw companies such as WBH Energy filing for bankruptcy
. A few others that met the same fate earlier include KiOR Inc., Endeavour
International, and Marion Energy. Consolidation is visible among major
players. For instance, the second-largest oil field services company
Halliburton Company bought the third-largest Baker Hughes. Ex... 阅读全帖

This code is the same as
data wbh;


set temp(in=B);
if x>2;
run;
Reason:
1. The variable x is already in temp, so temp(keep=x) does nothing.
2. No matter where you put the "set" statement, it always execute before the
"if" statement (as "if" is a loop over all rows, but set is not)
3. if you want to subset with "set", use "where" within set.

有意思。感觉是这样的
这里keep in 都是花招
if x > 2 决定了wbh 的 number of observation, say n
最后set temp(in=B), 读取了前面 n obs from temp
