Off-topic -- an eye on a stats presentation for clinicians?
I've got a 20 slide Powerpoint set up against the expected day someone
says "Mitch, could you talk for a short while to the residents on how
to use statistics?"
It looks good at this end, but I'd love to get at least one more pair
of eyes on it.
Any volunteers?

Think I'm sure, but confirm: lme4 vs. nlme
The impression I get from the list and the references I've perused is
that nlme is being phased out in favor of lme4, but lme4 still doesn't
have a complete feature set yet.
What I'm still fuzzy on, being a relative R newbie, is:
(a) what features in nlme are currently missing in lme4
(b) what's the projected time frame on getting them implemented.
If anyone can answer my naive

For MacBook, best way to do R?
I'm getting a MacBook and I'd like to stick with OS X rather than
convert it to Linux just yet.
However, my main concern is having decent performance.
What's my best option:
*use the existing binary for R?
*compile R fresh under OS X?
* install Linux and run R under that?
Does anyone have any recent experience they can share? Thanks!

any advice on web interfaces to R?
I saw http://cran.r-project.org/doc/FAQ/R-FAQ.html#R-Web-Interfaces
and I'm still not sure yet which platform (Linux, Windows, etc.) I'll
be working on -- and no, it's not under my control to pick.
I was wondering if anyone out there had good advice, that would save
me time and stomach acid, on how to set up a web browser to send a
list of commands to an R and put the resulting table

predict.gls choking on levels of factor
I've got a gls formula that's a mix of continuous and ordered variables.
I wanted to use gls because I wanted to use the varIdent structure.
Anyway, attempts to use "predict.gls" choke with the error that the
levels I use are not allowed for one of them -- the first one
alphabetically, so I'd guess the second would have the same problem.
So I have three linked questions --

Sample size calculation for differences between two very small proportions (Fisher's exact test or others)?
Hi,
I'm try to compute the minimum sample size needed to have at least an 80% of power, with alpha=0.05. The problem is that empirical proportions are really small: 0.00154 in one case and 0.00234. These are the estimated failure proportion of two medical treatments.
Thomas and Conlon (1992) suggested Fisher's exact test and proposed a computational method, which according to their table

Package for sample size calculation

Is anyone aware of a library for sample size calculation in R, similar
to NQuery? I have to give a course in this area, and I would like to
enable the students playing around with this.

libtheora test suite
Hi,
I just committed the framework for a test suite, and a couple of small
tests, to libtheora (changeset:9700).
The tests live in a directory called tests. When building with GNU autotools:
* 'make check' will run the test programs listed in the TESTS variable in
tests/Makefile.am . 'make check' will fail if any tests fail.
* 'make distcheck' will fail if any

UK VoIP-PSTN gateway recommendations
I'm looking for recommendations for UK-based VoIP-PSTN gateways.
They should ideally offer:
- IAX connection
- Multiple simultaneous calls on a single account
- Lower call rates than BT Business
- Auto-top up or invoicing in arrears
I can find several that offer one of these facilities, but none that offer
all.
Thanks!

Estimating credit card default probabilities.
Folks,
I am working on a credit card defaults and transition probabilities. For example a single credit card account could be in a number of states: up-to-date, 30, 60, 90 days in arrears or in default.
* Are there packages in R that do estimation of the transition probabilities given historical cohort defaults?
* Any pointers to papers specific to this type of estimation?
* Simulation of future

Power analysis for MANOVA?
Hello,
I have searched and failed for a program or script or method to
conduct a power analysis for a MANOVA. My interest is a fairly simple case
of 5 dependent variables and a single two-level categorical predictor
(though the categories aren't balanced).
If anybody happens to know of a script that will do this in R, I'd
love to know of it! Otherwise, I'll see about writing one
