Dear all, Is the restricted cubic spline function working properly in the glm model? We used glm(y~rcs(x,5), family=binomial) but it seems that for some theoretical reasons the rcs, restricted cubic spline function can not be fitted by a glm function. Is this correct? Regards, Jan ((Originally, we used lrm(y~ rcs(x,5)) but we couldn't find how to derive the AIC value of the fitted model.

Dear all, As I am new to the R community - although eager to advance- I would like to pose a question to the community. I have an SPSS file which I have imported it in R (with the read.spss command) which conists of scale (continuous) variable "adiponectin" and the corresponding categorical value "death" (0=No, 1=Yes). In all there are 60 observations (among which

Dear Dr ; I am a PhD student at Epidemiology department of National University of Singapore. I used R command (rcspline.plot) for plotting restricted cubic spline ??? the model is based on Cox. I managed to get a plot without adjustment for other covariates, but I have a problem regarding to adjusting the confounders. I applied below command to generate the matrix for

Hi, I'm trying to get the 'xts' library from CRAN packaged for Fedora 12, and one of its dependencies is 'Hmisc'. I have created a spec file for that using R2spec, but building it fails with something in building the manual pages: Warning: ./man/escapeRegex.Rd:22: unknown macro '\backslash' [similar warnings snipped] Warning: newline within quoted string at

I have an attached data.frame with a binary composite variable (comp) and a predictor (egfr). I am trying to plot a restricted cubic spline using: require (Hmisc) require (Design) rcspline.plot(x=egfr,y=comp,model="logistic",nk=5,knots=NULL, xlab="label1", ylab="Label2", plim=c(0,1), plotcl=TRUE, showknots=TRUE,

We just upgraded our server to run Mandrake 10.1. It is using kernel 2.6.8 and we are now using Samba 3.0.10. I am using the RCS commands on a Windows XP Professional computer. Before the upgrade, I had no problem checking files out with the "co -l" command no matter who owned the file. Now I get a "Permission denied" error unless I'm the owner of the RCS control

This patch (against unstable) makes sure that the skel/etc/init.d/rcS file is executable before building the final ramdisk image. This should fix the problem some people are having with their ramdisk builds. -- Dan Smith IBM Linux Technology Center Open Hypervisor Team email: danms@us.ibm.com _______________________________________________ Xen-devel mailing list

Hello, On Windows XP using R 2.4.0pat (2006-10-19 r39674) from CRAN (sorry, no r-devel) R CMD check of R CMD build --binary fails if package has RCS folder in data map. This does not happen on my Debian GNU/Linux box with R 2.4.0 (2006-10-03). Is this a bug? Here is the transript from the command prompt C:\Programs\R>R CMD check test * checking for working latex ... OK * using log

Hi all, I have fitted a gee model with the gee package and included restricted cubic spline functions. Here is the model: chol.g <- gee(SKIN ~ rcs(CHOLT, 3), id=ID, data=chol, family=binomial(link="logit"), corstr="exchangeable") To extract the log odds I use: predict.glm(chol.g, type = "link") Now I want to compute the logg odds for specific CHOLT values

In the book, "Regression Modeling Strategies", Frank Harrell uses the function rcs() often. The current version or R and Hmisc library don't appear to have this function. What is an appropriate substitute? Thank You -- Noah Silverman UCLA Department of Statistics 8208 Math Sciences Building Los Angeles, CA 90095 [[alternative HTML version deleted]]

Dear guRus, I am doing a logistic regression using restricted cubic splines via rcs(). However, the fitted probabilities should be nondecreasing with increasing predictor. Example: predictor <- seq(1,20) y <- c(rep(0,9),rep(1,10),0) model <- glm(y~rcs(predictor,n.knots=3),family="binomial") print(1/(1+exp(-predict(model)))) The last expression should be a nondecreasing

Hi, I read data from a file. I'm trying to understand how to use Design.rcs by using simple test data first. I use 1000 integer values (1,...,1000) for x (the predictor) with some noise (x+.02*x) and I set the response variable y=x. Then, I try rcs and ols as follows: m = ( sqrt(y1) ~ ( rcs(x1,3) ) ); #I tried without sqrt also f = ols(m, data=data_train.df); print(f); [I plot original

I was shocked to find no RCS on SXCE 107. I needed it to update some RCS archives I had copied over. No problem - go to sunfreeware and copy it over. No OpenSolaris branch? The Solaris 10 package should work. Only the package install appears to complete and does not - as documented only in a log file, not on my screen. OK then, the source for RCS should be easily compiled and installed, I

To keep track of an ongoing programming project, I would like to dump all my functions to individual ASCII files named xxx.R, yyy.R, etc. Presently I do so manually in order to use RCS (on a Linux machine), so I can keep track of all versions, differences, snapshots, etc. Is there any easy way to dump all functions in the workspace to individually named files? Thank you very much for

Hi, I have fit a series of ols() models, by group, in this manner: l <- ols(y ~ rcs(x, 4)) ... where the series of 'x' values in each group is the same, however knots are not always identical between groups. The result is a table of 'coefs' derived from the ols objects, by group: group Intercept top top' top'' 1 6.864 0.01 2.241 -2.65

Hi Apologies if this is a FAQ, I've tried Googling... I'm trying to set up CD-RCS on Windows boxes talking to our Linux Server (Samba 3.0.10-1.fc1.1.legacy). Apparently, the way this works is that it needs to be able to delete files that are read-only and not owned by you; they recommend that you set "delete readonly = yes" in the config file. The problem is that this
