Dear all, I have the following output generated by linear regression. Since there is only one regression intercept and one slope for one set of data, what is the meaning of std. error for intercept and that of slope? Thanks in advance. Sincerely, Minghua > data(thuesen) > attach(thuesen) > lm(short.velocity~blood.glucose) Call: lm(formula = short.velocity ~ blood.glucose)

I do not know if I have a problem or not. The R script at the end of this email seems to run properly and a I get a boxplot that looks proper but I get the long string of messages during execution of the script looking like: ... The following object(s) are masked from dat ( position 8 ) : sugar The following object(s) are masked from dat ( position 9 ) :

Dear All, using the example from the help of summary.rms library(rms) n <- 1000 # define sample size set.seed(17) # so can reproduce the results age <- rnorm(n, 50, 10) blood.pressure <- rnorm(n, 120, 15) cholesterol <- rnorm(n, 200, 25) sex <- factor(sample(c('female','male'), n,TRUE)) label(age) <- 'Age'

Hi guys, i'm trying to set up a server for Call of Juarez 2 Multiplayer on my Debian root. i installed the game with wine, installation worked. But now i cannot get the game startet. Is there anybody who knows how 2? The errorcode i get is: [start command (running as root)= wine CoJ2Game_x86_ds.exe] Code: fixme:actctx:parse_depend_manifests Could not find dependent assembly

Hello. One of my teaching assistants was experimenting and encountered unexpected behaviour with the lrtest function in the rms package. It appears that when you have a pair of non-nested models that employ an RCS, the error checking for non-nested models appears not to work. Here is a reproducible example. > library(rms) Loading required package: Hmisc Loading required package: lattice

Dear R-helpers, I'm having a problem in using plot.design in Design Library. Tho following example code produce the error: > n <- 1000 # define sample size > set.seed(17) # so can reproduce the results > age <- rnorm(n, 50, 10) > blood.pressure <- rnorm(n, 120, 15) > cholesterol <- rnorm(n, 200, 25) > sex <-

Hi, I am trying to get Hitman Blood Money working on my Ubuntu 9.04 computer. Here are my specs though they are most likely irrelevant: Ubuntu 9.04 Jaunty Jackalope: no modifications to the kernel or Xorg or anything. AMD Sempron 3100+: Worked fine in Windows, works fine now. 1GB DDR Ram: Single stick, memtested and passed. ATi Radeon 3650 HD (1gb): Rare version of the 3600 series. Works fine in

Hi, just making some experiments with design library i get an error if i want plot(fit) - show below from onlineHelp !? ..perhaps is here another mask problem?, but label from xtable which was my first problem is now off ! Thanks for advance & regards, Christian $ n <- 1000 # define sample size $ set.seed(17) # so can reproduce the results $ age <- rnorm(n, 50, 10)

Hi, I have what I believe is a repeated-measures dataset that I'm trying to analyze using lme(). This is *not* homework, but an exercise in my trying to self-teach myself repeated-measure ANOVA for other *real* datasets that I have and that are extremely similar to the following design. I'm fairly sure the dataset described below would work with lme() -- but it'd be great if anybody

dear£º in the example£¨nomogram£©£¬I don't understand the meanings of the program which have been marked by red line.And how to compile the program(L <- .4*(sex=='male') + .045*(age-50) + (log(cholesterol - 10)-5.2)*(-2*(sex=='female') + 2*(sex=='male'))). n <- 1000 # define sample size set.seed(17) # so can reproduce the results age <- rnorm(n, 50, 10)

Hi, When running z <- plot(fit, age=NA, cholesterol=NA, perim=boundaries, method='image') Legend(z, fun=plogis, at=qlogis(c(.01,.05,.1,.2,.3,.4,.5)), zlab='Probability') And after pointing the cursor to the plot() screen in R, I obtain the following message: Using function "locator(2)" to place opposite corners of image.legend Error in

I have fitted a proportional odds model, but would like to compare it to a continuation ratio model. However, I am unable to fit the CR model _including_ imputated data. I guess my troubles start with settuping the data for the CR model. Any hint is appreciated!

I have a plot produced by function bplot (package = rms) that is really a lattice plot (class="trellis"). It is similar to this plot produced by a very minor modification of the first example on the bplot help page: requiere(rms) n <- 1000 # define sample size set.seed(17) # so can reproduce the results age <- rnorm(n, 50, 10) blood.pressure <- rnorm(n, 120,

I''m a ferret newbie, so hopefully I''m missing something simple :) I am using ferret to index data about 36,000 products from a MySQL database. The index has one document for each product, with these important fields: id: the id (unique) of the product record in the database content: a concatenation of several bits of information from the product and associated records I

I've installed Hitman Blood Money (twice), using Playonlinux. The installation went (almost perfectly) well, but directx installation crashed. When I launch the game, it works fine but the image is upside down... I found a thread giving an answer (changing the OffscreenRenderingMode here : http://appdb.winehq.org/appview.php?iVersionId=4976) but (I think because of DX crash) there is no such

Hi, I just tried to get Blood 2 running on my Crunchbang Machine with WineHQ 1.0.1. I didn't encounter any problems during the intallation. But when I started the installed game some issues occured. 1st: When I'm in the configuration menu and try to change the keyboard settings, the ENTER-key stayes pressed constantly so that I can't change the key mappings as I'd wish to. 2nd:

Dear R-experts! I having trouble with the correct implementation of a mixed-model ANOVA in R. I my dataset subjects were tested in a cognitive performance test (numerical outcome variable 'score'). This cognitive performance test is devided into five blocks (categorical factor 'block'). All subjects were tested two times (in random order once following placebo treatment and once

I am trying to construct a graph of 6 box plots of blood pressures. I want them to be on a single set of axis and I want the SBP to be ontop of the DBP. I have an array bp with the data in it and I tried a[1,]<-c(145,60,147,62,140,57) a[2,]<-c(160,75,160,74,160,70) a[3,]<-c(140,55,140,65,142,55) boxplot(data.frame(a), main = "Blood Pressures", at=c(1,1,2,2,3,3),
