SiZer plots in R
Hello,
I am a graduate student at UNC Chapel Hill, and I am attempting to create a SiZer plot for a nonparametric analysis. I have found the file to use this program in Matlab, however I was hoping to find a package to use this in R. Does anyone know of a package that can create this type of graph?
Thanks,

trend turning points
Hi,
does anybody know of a nice test to detect trend turning points in time
series? Possibly with reference?

using kernel density estimates to infer mode of distribut ion
This might be of interest:
http://math.usu.edu/~minnotte/research/software/modetree.r
(I was not able to get to the link, but google has a cached version.)
Prof. Marron's SiZer maps may also be of interest, but AFAIK the code is in
Matlab only.

boundary correction - univariate kernel density estimation
Hey,
Does anyone know of a package in R that provides univariate kernel
density estimation with boundary correction ?
or how to easily extend an existing bivariate kernel density estimation
function (e.g. lambdahat in the spatialkernel package) with boundary
corrections to allow univariate density estimation?
Thanks a lot,
Steve B.

Estimating Weibull parameters
Hi R-Community,
I have a vector of Weibull distributed observations and I would like to
estimate the parameters "shape" and "scale" of the Weibull distribution.
Is there a way to do this in R?
Much thanks in advance,

Estimation of discrete unimodal density
Dear All,
A method for the estimation is univariate unimodal densities (with unknown
mode) is described in "Statistical Inference under Order Restrictions" by
Barlow et al.. Would anyone know whether there is an R-implementation
(preferably with reference) for the estimation of univariate discrete unimodal
densities (with unknown mode)? Thanks in advance for your help.

Percentile Estimation From Kernel Density Estimate
Has anyone developed a defensible method of estimating percentiles from a
univariate kernel density estimate? I am working on a problem in which the
density estimate is of interest, but I would also like to estimate the
value of the variable for which the distribution was, say, 0.20. I spent
some time searching the archives and found some message from 2006 that
implied such a method was not

FlexGridSizer question

I am trying to understand how FlexGridSizer works and I have written a small
test application using the latest wxRuby 0.4.0 on Win XP (Home).
I cannot get static text ''Week'', ''Day'' and ''Date'' line up above the OK button.
I have tried all combinations of ALIGN flags, but I either got the text sticking

Sizer question
First, Thank you, thank you, thank you for those who put wxRuby
together. I''m thrilled to be able to write GUI code in Ruby!
I''m hitting some confusion about how Sizers work. I''ve read the
tutorials and the section in the wxWidgets book but I still can''t
seem to figure this out.
Here''s an example of my code:

Adding sizers to other sizers doesn''t work
Hello all,
Running this on an Intel Mac

I''m having a heck of a time setting up a GUI with a differing number of
widgets per row, resulting in a differing number or widgets per column.
At first I tried to simply do something like the following:

Choosing a Sizer
Following alex advices, i''ve used both "text/textctrl.rb" and
"etc/threaded.rb" to build my first wxApp.
I''ve changed the Sizer type mainly (from "Wx::BoxSizer" to
"Wx::FlexGridSizer").
I didn''t find the way to let @log (Wx::TextCtrl) span 2 columns. At the time
of writing it''s growing only vertically.
And also how to get

[LLVMdev] clang and static functions
Hi,
Sorry for not being specific. I just wanted to know if there is any
way at all to force clang to generate intermediate code for static
functions when they are not being called anywhere inside the current
module. Other compilers seem to generate intermediate code (lcc, for
instance).
Thanks for your reply..Olivier.
Sincerely

wxruby unfriendly to other threads?
I''ve seen a few e-mails about multithreading with respect to wxruby
but nothing recent. Unless I''m mistaken, and that may be, there
still appear to be problems.
The following code seems to hang my spawned thread in favor of the
wxruby event loop:
Thread.new do
puts "in thread"
loop do
sleep 5
puts "looping"

wxSizerItem show() method
It appears from the wx 2.8.7 documentation that a wxSizerItem has a show()
method. But when I try to invoke it through wxruby, I get:
tasks.rb:56:in `do_btn3'': undefined method `show'' for
#<SWIG::TYPE_p_wxSizerItem:0xb5eedf44> (NoMethodError)
Is this just something that hasn''t been added because people don''t

sizer support for colspan > 1?
I see that GridBagSizer is not yet supported by wxRuby. Is there an
alternative to specifying that a widget spans more than one column? I
don''t see a way to do that in FlexGridSizer.

couple of questions
Hi folks
A couple of questions:
1) I seem to get funny artifacts in the display of TreeCtrl, ComboBox
and ListBox when the MDI child frame containing it is first painted (see
attached - it should be two-root treeview, unopened). I''m not sure if
it''s related to being in a MDI, but the controls sample looks OK. The
artifacts are cleared up when it''s repainted or

Proposal for an improved API for Sizer (and ToolBar)
Hi all,
This is a proposal for supporting keyword arguments to Sizer#add
following the thread below :
http://rubyforge.org/pipermail/wxruby-development/2008-March/001244.html
After a deeper look at lib/wx/keyword_ctors.rb and
lib/wx/keyword_defs.rb, I understood the whole thing :-).
I just reused and modified slightly the method args_as_list.
The new Sizer#add_item combines the features of add

How to test the statistical significance of the difference of two univariate Linear Regression betas?
How to test the statistical significance of the difference of two

Hi all,
There are two samples of data: D1 and D2.
On data D1 we do a univariate Linear Regression and get the coefficient
beta1.
On data D2 we do a univariate Linear Regression and get the coefficient
beta2.
How do I test the statistical significance of (beta1-beta2)?

Help with STL function to decompose
Hi everyone.
I'm having some troubles with STL function to decompose some data.
My issue is that I have monthly data from September 2005 up to August 2010
i. e. 60 observations.
I define it in the following way:
*u<-read.csv("C:/CELEBREX.csv",header = TRUE)
u.ts<-ts(u, start=c(2005,9), frequency=12)
*
The issue is that when I try to use
stl(u.ts, 'per')
Then the
