Need help in calculating studentized residuals/leverage values of non-linear model [nls()]
Hi there,
I hope I can get advice regarding the calculation of leverage values or
studentized residual values of a non-linear regression model. It seems like
rstudent() does not work on a nls object.
Many thanks in advance!
Best regards,

Enhanced version of plot.lm()
I propose the following enhancements and changes to plot.lm(),
the most important of which is the addition of a Residuals vs
Leverage plot.
(1) A residual versus leverage plot has been added, available
by specifying which = 5, and not included as one of the default
plots. Contours of Cook's distance are included, by default at
values of 0.5 and 1.0. The labeled points, if any, are those

leverage
Hi
Can anyone help with the technique of obtaining leverages from a
conditional logistic regression model? The code lm.influence does not seem
to work for this data.
Thanks

Which AR Interfaces Leverage PreparedStatements/Binds?
I could not find the answer to this in a few Google searches and thought I would ask.
So when are prepared statements best leveraged in ActiveRecord''s interface? I never really noticed before, but simple condition hashes or scopes do not pass down the binds so that prepared statements are leveraged. So a `Car.find(1)` would but things like `Car.where(:id => 1).first` do not. Is it a

detect outliers and high levarage points
Hi friends,
How to detect outliers and high leverage points for GLM ?
Could I use plot(model)
(i) "Residuals vs Fitted" graph to detect the outliers ?
(ii) "Residuals vs Leverage" graph to detect the high leverage points ?
And then remove those points from the data and re-run the model ?

[LLVMdev] Can I port LLVM as a source-to-source compiler?
Hello,
I am working in a project on a parallel programming language. I want to base
our language on Java or C/C++. But Java is preferred.
Many similar projects adopts a source-to-source methodology, e.g., Berkeley
UPC(using Open64), Titanium, and Rice University's Co-array Fortran. They
output C code with calls to the runtime. I think there are at least three
reasons: 1) using C as the

dynamic languages - how to leverage/make best use?
Hi,
Does anyone have any links to, or info on, how best to leverage the
power of a dynamic language. That is coming across from Java to Ruby
I''m now pondering what would be the typical scenarios where I could
actually call upon the power of a dynamic language. This info could be
in the form of best practice for dynamic language usage, or dynamic
language patters perhaps.

Multinomial Logit Models
Hi
I am wanting to fit some multinomial logit models (multinom command in
package nnet)
Is it possible to do any model checking techniques on these models
e.g. residual, leverage etc. I cannot seem to find any commands that
will allow me to do this.
Many thanks

Ah, you're in luck then: an MSP430 backend was checked in to SVN today
:) I don't think it's mature enough for general use yet, though.

Calculating Leverage or studentized residuals with gls
Dear colleagues, hi.
I am using the function gls in R-package nlme and I want to compute either the leverage values or the studentized residuals. Can any body tell me how can do that?

Control number of assets in resulting portfolio with optimizations using package fPortfolio
Dear All,
I am using package fPortfolio to run minimum variance portfolio
optimizations in R. I already know how to set portfolioSpecs, portfolio

type of constraints.
I have a timeSeries object with returns data for roughly 1.5k assets for 261

Leveraging newer CMake features for Language standards
LLVM currently has CMake code to try to detect the various options needed
to compile with C++11 support that has been around since prior to the CMake
version bump. One of the nicer features that came with the newer required
CMake version is that very thing. Rather than try to discern this yourself
CMake has the CXX_STANDARD and CXX_STANDARD_REQUIRED target properties. If

plot(<lm>): new behavior in R-2.2.0 alpha
As some of you R-devel readers may know, the plot() method for
"lm" objects is based in large parts on contributions by John
Maindonald, subsequently "massaged" by me and other R-core
members.
In the statistics litterature on applied regression, people have
had diverse oppinions on what (and how many!) plots should be
used for goodness-of-fit / residual diagnostics, and to my

indexing a subset dataframe
Hello
I am having problems indexing a subset dataframe, which was created
as:

Fitting a linear model revealed some data points which had high
leverage, so I attempted to redo the regression without these data
points:
>wasps.lm<-lm(r~Nt,data=waspsNoGV[-c(61,69,142),])

[RFC] FileCheck: (dis)allowing unused prefixes
...that right now would lead to 1500 test
failures.
To get there (thanks, maskray, for suggestion), we propose we:
* land D90281 where the flag is introduced, but is flipped to match today's
behavior
* employ a 'busy beavers' approach, where test maintainers patch their
tests:
- either leveraging the flag, to explicitly indicate that unused prefixes
is intended (i.e. add --allow-unused-patches=true); or
- fix the test (e.g. maybe there was a misspelling issue/omission/etc).
A spreadsheet with the failing tests is available here
