I have been trying to run a logistic regression using a number of studies. Below is the syntax, error message & data. Any advice regarding what I am doing wrong or solutions are appreciated, regards Bob Green > logreg <- read.csv("c:\\logregtest.csv",header=T) > attach(logreg) > names(logreg) [1] "medyear" "where" "who"

Hello, I was hoping for some advice in changing 2 defaults in a logistic regression. 1. It looks like the first category is the reference category? In the following syntax 'where' has 4 levels, how can I make the reference category the third category? model<- glm(cbind(sucesses, failures) ~ where + who + firstep + dxnarrow + age + sex + medyear, family = binomial, data=life.use)

Hi, Over the past six months, a MemorySSA-backed DSE implementation has been added to LLVM and it now covers almost all cases the existing DSE implementation does, plus adding a major new capability: eliminating stores across basic blocks. Thanks everyone involved with reviews, testing & patches! I think now would be a good time to start working towards switching to use MemorySSA-backed DSE

Hi Step 1: I create a data.frame called iolm. Step 2: I create a conditional subset i_wtr. Step 3: In this subset I add 0.3 to all values in the IOLM_AST column. Step 4: Now I am looking for the best way to Œmerge¹ the altered subset back into the original iolm data.frame ## STEP 1 >iolm ID IOLM_AST IOLM_AXIS 1 1 1.15 165.33 2 2 1.20 79.00 3 3 0.40

Hej, i need the which() funktion to find the positions of an entry in a matrix. the entries i'm looking for are : seq(begin,end,0.01) and there are no empty spaces i'm searching in the right range. so i was looking for the results R can find and i recieved this answer. for (l in

I want to compute a new variable (newvar) based on the values of two other variables (t1freq, t2freq).The two variables (t1freq,t2freq) are contained in a dataframe - study1dat <- read.csv("c:\\study1rb.csv",header=T) . I gather this computation can be done using Apply and I have run the following example from the help menu ## Compute row and column sums for a matrix: x

Dear R-help, I am trying to estimate a Cox model with nested effects basing on the minimization of the overall AIC; I have two frailties terms, both gamma distributed. There is a error message (theta2 argument misses) and I don?t understand why. I would like to know what I have wrong. Thank you very much for your time. fitM7 <- coxph(Surv(lifespan,censured) ~ south + frailty(id,

Hi there, I am currently working on my dissertation which is about testing the martingale hypothesis in the stock market using a methodology involving a range of variance ratio tests and multiple variance ratio tests. I contacted the author of a reference paper and I was told that the tests can be conducted using R programming language. Although I have gone through the theoretical background of

I have downloaded samba-2.2.2-sparc-solaris-2.8.pkg from your site and would like to install it to my unix server sun solaris 5.8. I am battling to use the pkgadd to install this package. Can you please help me in this regard as I have failed to find samba/docs/htmldocs/UNIX_INSTALL which is suppose to be instructions on how to install it on unix sun solaris. Thanking you in advance. Regards,

This is a minor question, but is there any difference between the two objects fred <- structure(1:10, dim = c(2,5)) and fred <- structure(1:10, .Dim = c(2,5)) Should I be using one rather than the other?

David's answers were correct. You are looking deep into the code when there is no reason to to so. 1. h(t|(X=x,Z=z)) = exp(Beta0 + XZBeta1) Most statisticians will tell you that this is an unwise model. The reason is that if you replace X with "X+1" the fit changes, which is almost never desirable. What if someone coded your dummy variable as 1/0 instead of 0/1 -- wouldn't
