difference between coxph and cph
Hi. I am using Windows version of R 1.8.1. Being somewhat new to survival analysis, I am trying to compare cph (Design) with coxph (survival) for use with a survival data set. I was wondering why cph and coxph provide me with different confidence intervals for the hazard ratios for one of the variables. I was wondering if I am doing something wrong? Or if the two functions are calculating hazard

R accuracy
Hello, I am trying to test the precision of R on datasets from The Statistical Reference Datasets Project http://www.itl.nist.gov/div898/strd/index.html and I don't manage to understand how R is storing its results. For example, I calculate a mean on the michelso dataset (100 values) and find: > m=mean(michel) > m V1 299.8524 > print(m,digits=15) V1 299.8524

specify GARCH model, using garchFit()
Hello, I’ve fitted a Garch(2,1) model with function 'garchFit()' from the package 'fGarch': > m1 <- garchFit(formula = ~garch(2,1),data = X,trace = F) * See 'summary(m1)' OUTPUT BELOW * PROBLEM: My alpha1 term is not significant and I would like to make a NEW model, say m2, that does not contain alpha1, but I am not sure how to specify this with the garchFit()

help with aggregate(): tables of means for terms in an mlm
I'm trying to extend some work in the car and heplots packages that requires getting a table of multivariate means for one (or later, more) terms in an mlm object. I can do this for concrete examples, using aggregate(), but can't figure out how to generalize it. I want to return a result that has the factor-level combinations as rownames, and the means as the body of the table

quantreg log and polinomial functions
I have two variables which show a typical quantile relation I would like to fit quantile regression models based on both logarithm and polynomial of second order functions within quantreg. Any help appreciated... Cheers Duccio Herewith the values: ------ var1 var2 0.96429 0.00138 1 0.02316 1.03145 0.09323 1.24088 0.77128 1.39869 0.86732 1.33728 0.63674 1.48299 0.96194

gam (mgcv) vs. multiple regression breakpoint analysis: inconsistencies?
Dear useRs, I have a question with respect to fitting a non-linearity using gam (mgcv package, version 1.7-16). In a study I'm currently conducting, I'd like to find out if there is a breakpoint after which the effect of Age of Acquisition (AOA) of the second language changes. I.e. if the slope of AOA before the breakpoint (at a certain AOA) is different from the slope past the

Question about logistic regression with ordered factor variable using the rms package (prev.Design)
Dear R users, Hopefully someone can help me, Maybe I just misunderstand the function in the package? I am working with a logistic regression model. Until now I always worked with the basic glm function, where for the model was: ¡§ glm( disease ~ test.value + cnct , family=binomial(link=¡¦logit¡¦) ¡¨. This works fine when test .value and concentration (cnct) are continuous vairables. However,

Nouveau doesn't detect DVI - Monitor
Hello, I'm new here, and I hope I can get any help. At first I thought this is a support mailing list, but it looks more like one for developers. I'm using Nouveau in ubuntu bionic. My problem is, when I connect a second Monitor to my Laptop on DVI-D connector, the monitor is not detected, Nouveau reports it as "disconnected". The Hardware works, because the BIOS uses the

Should we split llvm Support and ADT?
In my experience the buildsystem works fine in combination with tablegen (at least this aspect of it). The real problem here is that tablegen is just slow. Some of the X86 tables take indeed Last time I looked at it tablegen had still room to optimize the way it resolves class hierarchies and the variables within which it did basically one at a time, so it needed to traverse the hierarchies
