David, Duncan,
Hi
Following on David's rate argument
try (with modifications of pch and grid)
rate <- 1/4
shape = 8
rate = c(rep(1/4,100),rep(1/3,100))
I don't think the problem is related to the rate argument, which can
well be vectorized, as is the case for a number of arguments in distri
ata series seem to be reproduced twice, somewhat rescaled.
I don't understand what this mean.
What am I doing wrong?
Thanks a lot for your help,

In addition to classical and Bayesian inference on means, direct and
Bayesian inference on effect size and standardized effects are presented.

comparisons problem. Journal of Data Science, 4, 131-146.
Besides, it will give you the best constrained model (in terms of equal
means) for your data, and the probability that this model is the true
one. It is an elegant solution to the multiple comparisons problem.

It is unclear to me what you mean by "diagonal" but I suspect what
you're looking for is to locate projected points onto the unfolded curve.
That is exactly what coordinates on the principal curve would give you.

There are also some automatic search procedures of the best model, when

I am trying to learn Bayesian infe

Dear Kristi,
Also. can anyone recommend any resources to help SPSS users learn to things in
R?
You may want to have a look at the R2STATS package, a simple GUI for
linear models.

How can i replicate this in Linux:

I've tried source(tkgetOpenFile()) but with no luck

independent within your setting.
You should then be able to test various binomial or Poisson models with
the proper equality constraints.

Hello,
I would like to compute a weighted combination of matrices.
I have a number of matrices, arranged in a 3D-array, say:
z = array(rep(1:3,c(9,9,9)),c(3,3,3))
so that z[,,1] is my first matrix, and z[,,2] and z[,,3] the second and
third one, and a vector of coefficients:
w = rep(1/3,3)
