Greetings, I'm using MSM (mutli-state markov modeling) package to study the progression of fibrosis in U.S hepatitis C population. I find this is a very fascinating tool for an applied researcher like myself. I have a four stage progression only model without any absorbing stage, also assuming no misclassification error in the data for the time being. I also have a couple covariates in the

Hello After (simple random cluster) resampling with replacement I ran MSM function and I'm getting the following warning message ,which I'm not sure why. I don't have any absorbing stage set up in my MSM model. I have a 4 stage uni-directional MSM model. The only thing I see might be a problem is that when the last stage (stage 4 in my data) gets repeated it seems to give me a warning

Hi all, I have this microarray large microarray data set (ALL) from which I would like to subset or extract a set of data based on a factor ($mol.biol). I looked up some example of subsetting in, picked up two commands and tried both but I got error messages as follows > testset <- subset(ALL, ALL$mol.biol %in% c("BCR/ABL","ALL1/AF4")) >> Error in

I know this is slightly OT but folks discuss zfs compatible hardware here all the time. :) Has anyone used something like this combination? <http://www.cdw.com/shop/products/default.aspx?EDC=1346664> <http://www.cdw.com/shop/products/default.aspx?EDC=1854700> It''d be nice to have externally accessible CF slots for my NAS.

Hi, I am puzzled by the relationship between the p-values asociated with the coefficients of a univariate logistic regression involving categorical variables and the p-value I get from Fisher's exact test of the associated 2 x 2 contingency table. (1) The 2-sided p-value for the table is ~ 0.0015, whereas the p-value for the independent is 0.101 and the p-value for the intercept is

Using --existing, I would like to transfer files created by root to home dirs, where the files would be updated, but leave the user,group and perms as they were. ie root creates a new file on the sending system, rsyncs it to the home dir of the user, leaving the perms untouched. Seems there is no option for this - the users are not defined on the sending system. I cant do it backwards due to

(all in subject). If I want to do a PC analysis in a situation with missing data, I may want to have same flexibility as with "cor(.)", e.g., I may want princomp(x, ..., use.obs = "pairwise.complete") Actually, I may want even more flexibility. Currently, princomp(.) has if (cor) cv <- get("cor", envir = .GlobalEnv)(z) else cv <-

Hi, I have been using this website ( http://www.stat.pitt.edu/stoffer/tsa2/Rissues.htm http://www.stat.pitt.edu/stoffer/tsa2/Rissues.htm ) to help me to fit ARIMA models to my data. At the moment I have two possible methods to use. Method 1 If I use arima(ts.data, order=c(1,2,0), xreg=1:length(ts.data)) then the wrong value for the intercept/mean is given (checked on SPSS and Minitab) and

Hi! anyone knows where to get some info for kernel (maybe via sysctl) and or samba tuning for high performance ? I have read all the samba docs available, so aim looking for others tips besides the tcp tunings usually applied in smb.conf ? i am setting a server on a client site, with many clients (about 100), and i am using a real server hardware (an HP netserver with xeon procesor@2.8Ghz, 1Gig of

Howdy All, I am looking for some good tutorials (books, websites, whatever) for calculating/testing for Spatial Autocorrelation using R. Specifically, I am wanting to test for autocorrelation of a number of variables measured at a set of discrete locations. Up to this point I have been exploring the "spdep" package and I can get "moran.test" to work, but I am concerned that

Hello, I am using rsync for the first time. I have rsync 2.6.5 running on Solaris 9. It was built with gcc-2.95. We are experiencing a reverse lookup host error in rsyncd.log when the client with ip addy 180.X.XX.XX tries to access rsync on my Solaris box. 2005/08/11 14:30:13 [18092] rsync denied on module log from unknown (0.0.0.0) 2005/08/11 14:30:54 [18094] name lookup failed for 0.0.0.0:

Hello Rsync Community, I have been using rsync for several years to backup servers across an array of different areas. I have run into a new problem that I cannot find an answer for. We just recently purchased a Lacie 5Big Network RAID: http://www.cdw.com/shop/products/default.aspx?EDC=1596257 for one organization. We set up a test server to start backing up to this RAID via AFP.

I was wondering if someone familiar with survival analysis can help me with the following. I would like to fit a Weibull curve, that may be dependent on a covariate, my dataframe "labdata" that has the fields "cov", "time", and "censor". Do I do the following? wieb<-survreg(Surv(labdata$time, labadata$censor)~labdata$cov,

Dear all, I am now doing the logistic regression using R. (glm, family=binomial). Besides the standardize summary statistics generated from R, I am also interested in some more informations concerning the model fitting / prediction etc; Particularly I am interested in "pseudo R squar" and "C statistic". I searched the R- help and could only get very limited information. (Post

My previous post about prcomp and princomp was done in some haste as I had long ago indicated to Kurt that I would try to have this ready for the June release, and it appeared that I would miss yet another release. I also need to get it out before it becomes hopelessly buried by other work. Brian Ripley kindly pointed out some errors, and also pointed out that I was suggesting replacing some

Hi All, My attempts to build an R package on my Windows 7 computer using R V13.0 ir R V13.1 using R CMD build --binary <filename> have been failing at the penultimate step with the error message "running 'zip' failed" coming after the procedure has completed the MD5 sums step.The same build command on the same package completes successfully on my older Vista

Dear R, I have find a website where they report problem with ARIMA models in R. I run the examples there and they give result as shown on the website. Does this mean that nothing has corrected in R? Maybe you not have seen the page, but the author said he contacted you. Here is the URL: http://www.stat.pitt.edu/stoffer/tsa2/Rissues.htm I like to know your opinion. Mvh. Marie [[alternative
