Instrumental variable quantile estimation of spatial autoregressive models
Dear all,
I would like to implement a spatial quantile regression using instrumental variable estimation (according to Su and Yang (2007), Instrumental variable quantile estimation of spatial autoregressive models, SMU economics & statistis working paper series, 2007, 05-2007, p.35 ).
I am applying the hedonic pricing method on land transactions in Luxembourg. My original data set contains

lagsarlm - using mixed explanatory variables (spdep package)
Hello
I'm very new to R (which is excellent), so apologies if this has already
been raised. In the spdep package, I'm trying to undertake an
autoregressive mixed model using the lagsarlm function. This is working
fine, but there does not appear to be a method of including an explanatory
variable without it automatically being included as a lagged term. I'm
after something along the

Howdy R gurus !
I am newbie to R
I use R 2.0.1 in Windows XP. When I run R
I got the follwoing memory error.
My physical memory size is 3 Gb.
My R got the memory problem when it reached to

Internal DNS, update of reverse zone fails
Dear list,
one more problem.
I've setup my host running a samba addc controller. Samba version is
samba-4.11.6-r2. I've joined two win10 clients to my domain. One client
has a static ip, the other one was configured to ask my dhcpd-daemon for
an ip. Following the book from stefan kania, I modified my dhcpd.conf to
execute some scripts I've found on ArchWiki to add my

Using Lagsarlm
I'm trying to use the spdep package to calculate this:
y = rho W y + e
I don't want to use explanatory variables, just the lag from the dependent
variable.
How would I code this?

hello sir..
I am adolf and i am doing my final year engineering in NIT-Trichy.
I am going to do my project in job scheduling. Fot that i want to know
that how to extract the tol from the tcp/ip and some more details of
that. It will be very helpful for my project.
Bye.

summary( prcomp(*, tol = .) ) -- and 'rank.'
Martin, I fully agree. This becomes an issue when you have big matrices.
(Note that there are awesome methods for actually only computing a small
number of PCs (unlike your code which uses svn which gets all of them);
these are available in various CRAN packages).
Best,
Kasper

tol in prcomp
Hi there,
I was wondering if anyone could explain how you should set tol in the prcomp
function.
Using help(prcomp) explains it as "a value indicating the magnitude below
which components should be omitted. (Components are omitted if their
standard deviations are less than or equal to tol times the standard
deviation of the first component.) With the default null setting, no

Visual Studio project files in Speex 1.2beta
Hello,
I maintain audio processing part of code in sipXtapi -- open-source
VoIP library. And when I engaged Speex library, I found that its Windows
project files are not up to date and use strange settings. They miss several
source files and use single-threaded static runtime libraries. I see no benefits
of using static and moreover single-threaded libraries. In the modern world

summary( prcomp(*, tol = .) ) -- and 'rank.'
As I see it, the display showing the first p << n PCs adding up to 100% of the variance is plainly wrong.
I suspect it comes about via a mental short-circuit: If we try to control p using a tolerance, then that amounts to saying that the remaining PCs are effectively zero-variance, but that is (usually) not the intention at all.
The common case is that the remainder terms have a roughly

Speex.lib
Hi,
Thanks! can this program generate speex.lib instead of libspeex.lib??
the OpenSpeak link to speex.lib instead of libspeex.lib
I can compiled the libspeex.lib but not speex.lib.
Correct me if I am wrong
Thanks

summary( prcomp(*, tol = .) ) -- and 'rank.'
Following from the R-help thread of March 22 on "Memory usage in prcomp",
I've started looking into adding an optional 'rank.' argument
to prcomp allowing to more efficiently get only a few PCs
instead of the full p PCs, say when p = 1000 and you know you
only want 5 PCs.

Method dispatch S3/S4 through optimize()
I have been running into difficulties with dispatching on an S4 class
defined in the SparseM package, when the method calls are inside a
function passed as the f= argument to optimize() in functions in the spdep
package. The S4 methods are typically defined as:
setMethod("det","matrix.csr", function(x, ...) det(chol(x))^2)
that is within setMethod() rather than by name before

summary( prcomp(*, tol = .) ) -- and 'rank.'
I agree with Kasper, this is a 'big' issue. Does your method of taking only
n PCs reduce the load on memory?
The new addition to the summary looks like a good idea, but Proportion of
Variance as you describe it may be confusing to new users. Am I correct in
saying Proportion of variance describes the amount of variance with respect
to the number of components the user chooses to show? So
