Multiple comparisons with a glm
I've never seen anything written about multiple comparisons,
as in the multcomp package or with TukeyHSD, but using a glm.
Do such procedures exist? Are they sensible?
Are there any packages in R that implement such comparisons?
Thank you.

French Curve
Dear R experts,
Did someone implemented French Curve yet? Or can anyone point me some
papers that I can follow to implement it?
thanks in advance for your help.

FW: Re: Doubt about nested aov output
...As I understood it there are three different
rats labelled 1. There is a rat 1 on treatment 1 and a rat 1 on
treatment 2 and a rat 1 on treatment 3. Thus the levels of Rat do not
designate the "experimental unit", it is the levels of Treatment:Rat
that do this.

Installing Lindsey's packages
Dear r-helpers,
I downloaded http://popgen.unimaas.nl/~jlindsey/rcode/rmutil.tar (it
was originally .tgz, but got unzipped by my browser).
Can anyone give me detailed instructions on installing this and
Lindsey's other packages on R version 2.4.0 (2006-10-03)---(powerpc-
apple-darwin8.7.0, locale: C)?

Sweave scientific real display format (e.g. 5e-12)
Dear All,
I couldn't figure and couldn't google out how to make construct a pair of
\Sexpr s or a LaTeX macro that would include
5\cdot 10^{-12}
into the LaTeX output istead of
5e-12 .
Any ideas?
Thank you

Plotting a segmented function
This might be a trivial question, but I would appreciate if anybody
could suggest an elegant way of plotting a function such as the
following (a simple distribution function):
F(x) = 0 if x<=0
=(x^2)/2 if 0<x<=1
=2x-((x^2)/2)-1 if 1<x<=2
=1 if x>2
This is just an example. In this case it is a continuous function. But
how to do it in general in an elegant way.

Tobit estimation?
Folks,
Based on
http://www.biostat.wustl.edu/archives/html/s-news/1999-06/msg00125.html
I thought I should experiment with using survreg() to estimate tobit
models.
I start by simulating a data frame with 100 observations from a tobit model
> x1 <- runif(100)
> x2 <- runif(100)*3
> ystar <- 2 + 3*x1 - 4*x2 + rnorm(100)*2
> y <- ystar
> censored <- ystar <= 0

how to adjust link function in logistic regression to predict the proportion of correct responses in 2AFC task?
I have would like to use logistic regression to analyze the
percentage of correct responses in a 2 alternative forced
choice task. The question is whether one needs to take into
account the fact expected probabilities for the percentage of
correct responses ranges between 0.5 and 1 in this case and
how to adjust the link function accordingly in R (see details below).

Generating correlated data from uniform distribution

I want to generate two random variables (X1, X2) from uniform

x*x*x*... vs x^n
Hi
I have been wondering if there one can speed up calculating small powers
of numbers such as x^8 using multiplication.
In addition, one can be a bit clever and calculate x^8 using only 3
multiplies.
look at this:
> f1 <- function(x){x*x*x*x*x*x*x*x}
> f2 <- function(x){x^8}
> f3 <- function(x){x2 <- x*x;x4 <- x2*x2;return(x4*x4)}
[so f1() and f2() and f3() are
