We have a 4-week alpha/beta/RC period every 6 months for testing before a 2.x.0 release. This is announced here, and we get very little response. I expect the testing window for R 2.13.0 to be Mar-Apr. That said, we do quite extensive testing on the main platforms (ix86 and x86_64 Linux,

[Rd] Problem with confint function

2011-02-11 Thread Kino Aguilar
Hi, I am currently doing logistic regression analyses and I am trying to get confidence intervals for my partial logistic regression coefficients. Supposing I am right in assuming that the formula to estimate a 95% CI for a log odds coefficient is the following: log odds - 1.96*SE to log odds +

Re: [Rd] Problem with confint function

2011-02-11 Thread John Fox
Dear Kino, The confidence intervals that you've computed yourself are based on the Wald statistic, while confint() computes confidence intervals based on the likelihood-ratio statistic, by profiling the likelihood (see ?confint and click on the link for confint.glm). Basing confidence intervals

[Rd] R limits documented?

Is there documentation on R limits? That is, max matrix size, etc.? Diagnostics when limits are exceeded are not always meaningful. For example: x - rep(0,5*5) Error in rep(0, 5 * 5) : invalid 'times' argument In addition: Warning message: In as.vector(data) : NAs introduced by
