What PRECISELY is the dfbetas() or lm.influence()$coef ?
Hello. I want to get the proper influence function for the glm coefficients in R. This is supposed to be inv(information)*(y-yhat)*x. So I am wondering what is the exact mathematical formula for the output that the functions: dfbeta() OR lm.influence()$coefficients return for a glm model. I am confused because: 1. Their columns don't sum to zero as influences should. 2. They

Help with time varying covariate-unfold function
Hello All, I am trying to use the unfold function in RcmdrPlugin.survival library, which converts the survival data with time varying covariates to the counting process notation. The problem is somehow, the event indicator created is not correct. Below is the data, I am trying to convert: CASE TRT FAILTIME FAILCENS SEX AGE IGG0 IGG28 IGG42 IGG84 IGG364 26003 A 11.2033

Formula parsing and updating
Hi all, I can't come over a problem with formula. Suppose I have a coxmod model with the following formula: > somemod$formula Surv(lebzeit, tot == 1) ~ sex + (alter >= 65) + diff3k + zelltyp_k_c + q_nuc_3k + kar_k80_g80 + stadium and I want to drop the stadium explanatory variable from the model with > update(somemod, ". ~ . - stadium") I get the following messages:

Eliminating For Loop in Comparison and Replacement
Hi, I have two dataframes: (Fails, Refurb) each is identical in structure. The structure has columns consisting of the following: EquipID(Equipment Identification), CustID(Customer Identification), FailTimes(Time Equipment Failed). The for loop below is part of a larger Monte Carlo simulation involving the reliability of equipment and customers. for (i in 1:length(Fails$CustID)){ j<-1

problem with normalizePath()
I wonder if this could be related to the issue that I submitted to bugzilla about two months ago? ( https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=17159) That is to say, could it be that it's treating the first path after the single backslash as an actual directory, rather than as the name of the share? -- Evan Cortens, PhD Institutional Analyst - Office of Institutional Analysis

survival::clogit, how to extract residuals for GOF assessment
Hi Folks, Hopefully this question has enough R and not too much stats to be appropriate for this list. Based on,* Hosmer et al. 2013. Logistic regression for matched case-control studies. Applied Logistic Regression *(eqtn. 7.8)*, *I am assessing GOF of conditional (or matched) logistic regression models with the *standardized Pearson residuals*. The authors define ?large? as delta chi-squared

problem with normalizePath()
In researching another issue, I discovered a workaround: the network drive folder needs to be mapped to the local PC. setwd("//Hzndhhsvf2/data/OCPH/EPI/BHSDM/Group/Michael Laviolette/Stat tools") df1 <- readxl::read_excel("addrlist-4-MikeL.xls", 2) # fails, throws same error df2 <- readxl::read_excel("Z:/Stat

calculating martingale residual on new data using "predict.coxph"
Hi list, I was trying to use "predict.coxph" to calculate martingale residuals on a test data, however, as pointed out before http://tolstoy.newcastle.edu.au/R/e4/help/08/06/13508.html predict(mycox1, newdata, type="expected") is not implemented yet. Dieter suggested to use 'cph' and 'predict.Design', but from my reading so far, I'm not sure they can

problem with normalizePath()
I found this as well. At our institution, our home directories are on network shares that are mapped to local drives. The default, it appears, is to set the location for libraries (etc) to the network share name (//computer//share/director/a/b/user) rather than the local drive mapping (H:/). Given the issue with dir.create(), this means it's impossible to install packages (since it tries to

How to display model data along with the images from the file store
I have a controller that is similar to the one below. But how do I use the send_file method inside the controller so that I can display images as well as display the text. For example, if my controller name is called images and I am displaying all the attributes about the image like artist name, song title and wanted to use their band picture also in the same controller?

Passing parameters along
I have a simple form that asks for three variables: column, operation, and data, which will allow my user to say things like "username starts with A" or "email address contains hotmail". This all works. I build up a conditions string and feed it into a paginator. What I''m working on now is making sure that my next and previous page buttons continue to work.

XEN images and XFS don't seem to get along
Hello listmates, It appears that on the second machine in a row (CentOS 5.5, 32 bit) if I am trying to place a VM into a file located in XFS the machine just hangs (the host machine, not the VM). If I place the VM in a raw device or in a file in ext3 all seems to work perfectly. Is that just a coincidence or is there a reason for this madness? Thanks. Boris.

OT Nice IBM 1U Server Gets Along w/Old and New Digium Boards Cheap X305 $199
Just an FYI on a great server for cheap if anyone is looking for a solid Asterisk platform. I don't work for these guys or have any affiliation, I just saw this deal and used to use these and the X306s for Asterisk deployments because they were trouble free as far as hardware, IRQs, and OS. They were ~$1,000 a couple of years ago. It is a refurb so YMMV.
