发帖数: 80 | 1 Hi, I used Dr. Harrell's rms package to make a nomogram.
Below is my code for nomogram and calculate total points and probability in
original data set used for building the nomogram. My question is how I get
the formula for calculating the survival probability for this nomogram. Then
I can use this formula to do validation by using other data set.
f1 <- cph(Surv(retime,dfs) ~ age+her2+t_stage+n_stage+er+cytcyt+Cyt_PCDK2 ,
data=data11,
surv=T, x=T, y=T, time.inc=5)
surv<- Survival(f1)

温哥华 -- 素。食尚
文/林欣颖 Feb 2008
温哥华概况和观光资源
温哥华叁面环海，因有太平洋季风和暖流调节，以及壮丽的海岸山脉作爲天然屏障，全
年气候温和，四季景观不同，魅力非凡，为加拿大西岸最大的经济文化中心，也是全国
第叁大城市，仅次於多伦多、蒙特利尔。
温哥华不但拥有得天独厚的大自然美景，其丰富的人文色彩、来自世界各地移民的多元
文化特色，都令人深深着迷，流连忘返。在2006年的“世界最佳居住城市”评选中，温
哥华位居全球第叁位；而在英国著名的杂誌“The Economist Intelligence Unit”（经
济学人智库）上，更四次荣获第一名为世界最适合居住的城市。最令人兴奋的是，2010
年冬季奥林匹克运动会也将於温哥华举行，热闹登场！
当然，说到温哥华，所有老饕们一定不会忘记她的“吃”。除了拥有优美闲适的环境，
温哥华的“美食”也是闻名遐迩。每每出国旅遊，认识的新朋友一听到我住温哥华，第
一句就是说，“哇，温哥华的东西很好吃、很道地，据説一些很厉害的香... 阅读全帖 |

最近升级音响系统，最后选了这款。
特色是基本上所有的接口都配全乐（AuxIn/USB/SD/内置Mic/Sub），支持Bluetooth，
可以播放flash里的MP3/WMA（好像还支持IDv3Tag啥的，不过对我来说无所谓），支持Windows/DOS文件系统（长文件名没有试）。功率么
，内置Amp可以做到4x45w max, 4x21 rms,基本够用了； 前面Detachable Panel,后面带电动天线和
Dimmer控制，都还算中规中矩。另外价格便宜，在walmart.com 上~$160（Local Store
pickup）,比他们自己的网站都便宜(Walmart的砍价能力真是没说的)。
昨晚试了SubWoofer和蓝牙，SubWoofer是RCA输出，需外接Amp(一般都是这样的)。没试
内置麦克，而使用了附带的外接麦克（别在Console的空调进气口）。通话效果不错，
没有噪音和回响，对方也没有感到与直接用手机通话有任何区别。
缺点么，Feature里还少了Satellite Ready，不过考虑已有的功能/接口及其价格，也
还可 |

发帖数: 8077 | 11 to be frankly, I don't think a car audio should have such big output. heat
will be a big problem, distortion will be huge, too
think about hi-end Hi-Fi amp at home, 100W per channel for a steoro amp
would be very good and it will blow your ear if you turn it into max. your
1kW RMS output is already larger than a 7.1 Channel Receiver with 100W per
