[R] Sample size: epiR survival

Hallo! Does anybody know what epiR calculates with method = "survival"? library(epiR) library(survival) epi.studysize(treat = .65, control = .50, n = NA, sigma = NA, power = 0.80, r = 1, conf.level = 0.95, sided.test = 2, method = "survival") Because I found out that method "proportion" does n

Re: [R] help on understanding a code

You haven't provided us enough information. You should also provide examples where we can access all the called objects; for example, ttest() is not a built-in function, so we have no idea what it is. Same goes for dat and y. On Tue, Jun 2, 2009 at 11:43 AM, Hongyuan Cao wrote: > Dear R user, > >

[R] Sample size - proportion continuity correction

Yes, Tinn-R is great for windows users. However, if you work under different OS, it would be great to have an OS-independent editor. Ronggui 2009/6/2 Bos, Roger : > I have not seen Tinn-R mentioned so I will mention it.  Its worked great for > me.  Eclipse is a nice IDE, but its more complicated

[R] help on understanding a code

Dear R user, I am trying to understand this following code. Basically it's using a permutation method to calculate p value. But I would like to know exactly how the permutation works. #calculates null statistics tt0 <- 0 set.seed(123) B <- 100 for(i in 1:B) { v <- sample(y) tt0 <- c(tt0,ttest(dat

The answers differ by a factor of 19/20, ie, (n-1)/n, so it is presumably the choice of denominator for the variance that differs. -thomas On Tue, 2 Jun 2009, Liviu Andronic wrote: Dear all, Does this make any sense: var() = cov() != acf(lag.max=0, type="covariance")? I have daily
