1. Compiling S? (score: 1): Author: Doug Moog <dbm3@po.cwru.edu>; Date: Fri, 16 Feb 2001 11:06:55 -0500; I have to provide an exceutable version of a program I currently have written in S using SPlus 2000 for Windows. I assume this means I have to rewrite it in another language, but is there any chance; /archives/html/s-news/2001-02/msg00150.html (6,266 bytes)
2. Re: stepwise regression (score: 1): Author: Doug Moog <dbm3@po.cwru.edu>; Date: Mon, 20 Nov 2000 11:06:47 -0500; Thanks, I very much appreciated that discussion. My question is "what is data mining anyway?" That is, I know in general what it is, but not how to do it. A collection of automatic techniques provide; /archives/html/s-news/2000-11/msg00187.html (6,747 bytes)
3. [S] pvalue for regression slope w/ autocorrelation (score: 1): Author: Doug Moog <dbm3@po.cwru.edu>; Date: Wed, 14 Jun 2000 16:28:05 -0400; Is there a function in splus which calculates pvalues or confidence intervals for linear regression slopes? I'm particularly interested in one which corrects for autocorrelation in the data. Thanks D; /archives/html/s-news/2000-06/msg00094.html (7,321 bytes)
4. [S] Pr(F) in anova() (score: 1): Author: Doug Moog <dbm3@po.cwru.edu>; Date: Tue, 07 Sep 1999 13:41:44 -0400; I'm running Splus 2000, Windows 95, and I'm confused about what I'm reading in the output of anova() applied to a linear model, lm(). I will run a model with one or more terms and get a certain set; /archives/html/s-news/1999-09/msg00052.html (7,794 bytes)
5. RE: [S] Pr(F) in anova() (score: 1): Author: Doug Moog <dbm3@po.cwru.edu>; Date: Fri, 10 Sep 1999 14:32:01 -0400; I asked: I received the correct explanation from Alan Donald, Dave Krantz, George Tomlins, Bill Venables, and Nick Locantore, whom I quote: Thanks to all who answered. I know I'll be corrected by the; /archives/html/s-news/1999-09/msg00105.html (10,694 bytes)
6. [S] using apply() with update() of an lm()? (score: 1): Author: Doug Moog <dbm3@po.cwru.edu>; Date: Wed, 15 Sep 1999 15:56:42 -0400; I'm totally perplexed. The following (where my.df is a numeric data frame): x.null <- lm(my.df[,1]~1, data=my.df) apply(my.df[,-1], 2, function(x,y) {x.new_update(y,.~.+x); sum(residuals(x.new)^2)},; /archives/html/s-news/1999-09/msg00159.html (7,794 bytes)
7. [S] interpreting p-values from lm() results (score: 1): Author: Doug Moog <dbm3@po.cwru.edu>; Date: Tue, 09 Feb 1999 08:35:25 -0500; I'm running a mutliple linear least-squares regression using Splus 4.5 under Windows 95. I am wondering why I get radically different p-values using the t statistic for some terms than anova() gives; /archives/html/s-news/1999-02/msg00030.html (8,998 bytes)
8. Re: [S] interpreting p-values from lm() results (score: 1): Author: Doug Moog <dbm3@po.cwru.edu>; Date: Tue, 09 Feb 1999 14:25:26 -0500; Many thanks to those who answered my query. The part I hadn't figured out was that the t-test applied to a model containing all the other variables. Even I was able to figure out that the F-test was; /archives/html/s-news/1999-02/msg00038.html (8,089 bytes)
