Dear list, I'm trying to understand what kind of uncertainty intervals are plotted for survival::survfit.coxph when 'conf.int=TRUE' is called, e.g.: f <- coxph(Surv(futime, fustat) ~ age, data = ovarian) s <- survfit(f, newdata=data.frame...

Hi, I'm using survreg() from the survival package for parametric survival regression (modelling inter-arrival times of patients to a waiting list as exponentially distributed, with various regressors such as queue size and season). Does anyone know which algorithm...

Hi, I'm using latex() from Frank Harrell's Hmisc library to produce LaTeX files. By default, it calls xdvi and displays the dvi. How can I make xdvi not show? I couldn't find a clue in the extensive...

Hi, I'm performing (blocked) 10-fold cross-validation of a several time series forecasting methods, measuring their mean squared error (MSE). I know that the MSE_cv is the average over the 10 MSEs. Is there a way to...

Hi, I'm trying to plot several lag.plots on a page, however the second plot replaces the first one (although it only takes up the upper half as it should): par(mfrow=c(2,1)) a<-sin(1:100...

Hi, I'm interested in doing mixed-effects logistic regression on gene expression data (genes in each batch as fixed effects, and different batches as random effects). The data has many times more variables than samples. This calls for a...
