发帖数: 72 | 1 请教各位大虾，
需要 convert R package to Splus,
按照Instruction Step By Step， 把package “fBasics” download 下载安装
最后一步 Check
at splus commands console:
=========================================================
> Splus CMD check fBasics
Problem: Object "Splus CMD check fBasics" not found
Use traceback() to see the call stack
=========================================================
At the DOS prompt:
=========================================================
C:\Program Files\TIBCO\splus81>Splus CMD check fBasic |

区别大了，简单说SPLUS/R 更趋于一种语言，而SAS
的灵活性差一点，有许多现成的procedures
可以使用，对于简单的分析很有用，但output比较难懂。用SAS作图比较复杂，不如SPLUS
/R。R 是免费的，不过好多函数在R和SPLUS中不通用。
希望各位大虾继续补充。 |

发帖数: 8 | 3 I am working on my paper with Splus, and I need to write Splus code
for the following double integral:
integral(0, 1)integral(0,1) {-(1+gamma*k)
((1-(1-u)^k)^(-gamma)+(1-(1-v)^k)^(-gamma)-1)^(-2-1/gamma/k)} du dv
I wouldn't go through if I couldn't figure out the code. So your kind reply
would be highly appreciated. |

发帖数: 10 | 4 I need to work on something about clustering. One professor suggested
me three statistical packages: Splus, SAS, and Matlab.
My question is:
1. What are Splus, SAS?
2. I have not found any toolbox or function about statistics clustering in
Matlab so far. Can anyone give me brief instruction?
3. What are their respective advantages and disadvantages?
4. Which one of these three is most powerful and modern in statistics? |

S0是初始价格，r是利率，sigma是波动率，T是到期日，K是执行价，hsigma是算vega用

发帖数: 22 | 13 I use SAS 90% of the time at work because we deal with FDA, and SAS is a
validated software. Splus is also a validated software, which is also OK
with FDA. But SPLUS is essentially R, except that R is free and SPLUS is not
. R does all things SPLUS or SAS can do, only that it's more powerful and
flexible, IMHO. |

After read all those posts, it seems that few people here really know SAS and
Splus, especially SAS. "Splus vs SAS 就象 Matlab vs Excel" is so wrong.
For statistical application, both SAS and Splus are easy to use. If you wanna
use statistical methods, like linear regression, it's same easy for both of
them. Just run the procedure or function, they both have good statisic package
for all the classic and modern statistical methods. The only thing matters |

发帖数: 33224 | 15 没有open source 哪来的R呀。R才15年左右吧，已经彻底改变了统计计算领域。（其实
比SAS还惨的是Splus呀。很多人不知道啥是SPlus了吧。）
至于精确度和科学发现，在于使用的人是不是good statisticians。
统计的问题是很难证实，但是可以证伪。统计可能没发现啥，但是能指出很多伪科学。 |

fas也有Splus, 这玩意儿我熟多了
就是hist(mydata)
当然别忘了打开motif()或X11()或openlook()

postscript("myhist.ps")
hist(mydata)
dev.off()
可以用help(hist)选option |

发帖数: 2174 | 21 for computation intensive stuff, you'd better consider other language, such

I used to work on MCMC EM algorithm on NLME model with missing data for my

wrote the core function in Fortran, and then compiled it and loaded the
binary into Splus. |

发帖数: 30 | 45 我知道为何多数大学开头不用SAS而用其他的统计软件（比如R，S-plus,SPSS，或
Matlab）。那是因为SAS是商业软件，使用者要付费。但也正由于SAS是商业软件，所以
SAS才是工业界的正式使用的统计软件（从而有工作机会）。
SAS的难度与Splus相当（或容易稍许）。会SPSS或Matlab的，学SAS也就不难。
一天，我见几个SAS同事在议论： SAS与JAVA或C#相比，哪个容易学？结论是，学SAS当
然比JAVA以及C#要容易得多（但精通都难）。
为何高年纪的数学才能选？--大学里就是把SAS作为数理统计课的计算器。--但这只是
SAS的应用的一个方面。
