similar to: Measure of linearity between two variables?

Hello, I am wondering if there is an easy way to combine loess() with glm() to produce a locally fitted generalised regression. I have a data set of about 5,000 observations and 5 explanatory variables, with a binary outcome. One of the explanatory variables (lets call it X) is much more predictive than the others. A single glm() regression over the entire data set produces rather poor results,

[sorry, but this is a re-post - I forgot to set the subject line the first time around] Hello, I would like to access an Oracle database running on Solaris from R on my linux desktop. I have had a look at the R Data Import/Export manual, and downloaded RODBC and unixODBC, but I am still quite confused about how to proceed. It appears to me that I still need to get an Oracle ODBC driver, and

Things consider problems with sftp software - sftp manually first time to accept the fingerprint and anytime software is updated on host. - no ascii mode only binary - no verbose or indication of bytes transfered (you would do an ls after sftp is done) - no mput or mget (this may be a show stopper) but could script could generate itself with all the filenames takes coding.

Hello, I have installed the ROracle and DBI packages, and I want to access an Oracle database that is not on the same machine as the one I am running R on. I can access the database remotely with perl DBI and Java JDBC. Does anyone know if this is possible using R DBI/ROracle ? I have looked through the documentation and also tried to guess at things which might work, but with no success. I

Hi, I'm running Samba as a glorified NAS at the moment - to begin with, I have an ext3 storage partition, /storage. In this is a directory, /storage/Personal, which has its own Samba share (also Personal). At this point, dos attributes using filesystem xattrs work beautifully. The problem comes when I start to fiddle further... I have a Novell NetWare filesystem (ncpmount) mounted at

Hello, I have a 2 factor linear model, in which the only terms I am interested in estimating and testing are the interaction terms. I want to control for the main effects but have no interest in estimating or testing them. However, I would like an estimate of the interaction effects for every level of the interactions, whereas what I get is one fewer estimate than this, with the first level

I had run into problems when compiling some contributed packages to an installation of R 1.40 by fink on MacOS X. Namely, packages KernSmooth (2.22-7) and cluster (1.4-0) would not find required libraries, though those were present on the system. Jeff Whitaker, the maintainer of the R fink packages, kindly sent me this: > Kaspar: It's not looking in /sw/lib, where the libs are (the

Hello, This is an RFC for adding intrinsics which perform saturating signed/unsigned left shift. There is currently a patch on Phabricator here: https://reviews.llvm.org/D83216 The intrinsics are of the form i32 @llvm.sshl.sat.i32(i32, i32) i32 @llvm.ushl.sat.i32(i32, i32) <4 x i32> @llvm.sshl.sat.v4i32(<4 x i32>, <4 x i32>) <4 x i32>

Hi, I am intending to submit some patches that enhance the SPARC code generator. Is this the preferred place to post them, or should I send them to llvm-commit? Martin

Each register is a 4-component (namely, r, g, b, a) vector register. They are actually defined as llvm packed [4xfloat]. The instruction: add_sat r0.a, r1_bias.xxyy, r3_x2.zzzz Explaination: '.a' is a writemask. only the specified component will be update '.xxyy' and '.zzzz' are swizzle masks, specify the component permutation, simliar to the Intel SSE permutation

Dear R-helpers, First of all, sorry for those who have (eventually) already received that request. The mail has been bumped several times, so I am not sure the list has received it... and I need help (if you have time)! ;-) I have a very simple question and I really hope that someone could help me I would like to estimate a simple fixed effect regression model with clustered standard errors by

Actually the problems that Tzu-Chien Chiu are encountering are similar to what should be done for generating SSE code in the X86 backend and also other SIMD instruction sets. I think LLVM neeeds to add instructions for permuting components, extracting and injecting elements in packed types. If the architecture has instructions which can do permutations for each instruction (for example

demo("graphics") notes that a circle (piechart) is a test of monitor linearity. With a new monitor on a new linux system with R-0.65.0 I get an ellipse. This is not a pincushion effect and the major/minor axis ratio is constant over size and screen location variation. Is this a hardware problem or are there alternative possible explanations to explore? Gordon M. Harrington Mail: 3720
