wilcox.test construction in r
Hi, I am very confused with constructing the wilcox.test in R. I have two populations 'original' and 'test'. I want to know if the 'test' is generally 'lower' than original. I use alpha of 0.05. So do I write the function as wilcox.test(original, test, alternative="l")? or wlcox.test(original, test, alternative = "g")? or wilcox.test(test,

Generalized Estimating Equations and a Reviewer Question I can’t answer
I am using the R statistical package in a pretty straightforward manner, just interested in getting summary statistics and reliable estimates of means, variances, confidence intervals, p-values using standard tests, etc. I've been using the generalized estimating equation package because I often deal with repeatedly sampled pairs of data from the same source, and my reading (and my

Random covariate in survreg (Survival)
Dear R Listers- I am attempting to analyse the survival of seeds in cages (exclosures) that differ in their permeability to rainforest mammals. Because I did not observe the moment of seed disappearance, my data is interval censored. This limits my options for analysis (as I understand it) to survreg, in the survival package. Because I repeated the experiment in 8 sites, I have a random

Hi, It is non trivial to recompute summaries (which is why we have summaries in the bitcode in the first place by the way), because bitcode is expensive to load. I think shipping two different variant of the bitcode, one with and one without summaries isn't providing much benefit while complicating the flow. We could achieve what you're looking for by revisiting the flow a little. I

Hi David, Thank you so much for your reply! >> You're dealing with a situation where you are shipped BC files offline and then do one, or multiple builds with these BC files?
