Hi,
Would you help me solve the following question? Thanks.
Question: If I try to set the probability=0.05 and find the approximate x. (The answer should be somewhere between 2.1782 and 2.1783.)
I write about this R program as follows but I don¡¦t know how to get the value of x which is between 2.1782 and 2.1783.

about mix type clust algorithm
Hi:
I have tried to find the appropriate clust algorithm for mixed type of data.
The suggested way I see is:
1. use daisy to get the dissimilarity matrix
2. use PAM/hclust by providing the dissimilarity matrix, to get the clusters
but by following this, when the data set grows bigger say 10,000 rows of data, the dissimilarity matrix will be O(n^2), and out of memory will occur.

questions about R
Hi,
I try to compute critical value for multivariate normal distribution, and I find the crit(fit, const = c(0, 1), d = 1, cov = 0.95, rdf = 0) which seems to compute critical value. However, I can't compute right critical value for multivariate normal distribution which I want. I don't know how to solve my question. I send my question in the file. Would you help me to solve it, please?

readJPEG function cannot open jpeg files
I installed jpeg package and tried to use
kim<-readJPEG("kim.jpeg") to read in a jpeg file, but R gave me an error:
Error in readJPEG("kim.jpeg") : unable to open kim.jpeg
I already put "kim.jpeg" in Rstudio's default working directory: "E:\home
work\Rstudio". So I don't think it's a problem caused by omitting the file's
path. But I

Clustering with R - efficient processing of large sparse data sets (text data)
I checked the R procedure HCLUST (hierarchical clustering) but it
looks like it requires a full triangular n x n similarity matrix as
input, where n = number of observations. The number of variables is
200.
My data set has n = 50,000 observations (keywords), and I use ad-hoc
similarity measures, not available in R, to measure keyword
similarity. Here, the vast majority of the n x n similarities

Xen and the InfiniBand
Hi, all,
Is the Xen currently compatible with the InfiniBand? I found some
information about the Smart I/O module, but it was posted in 2006. Is the
module still maintained? Or, are there any up-to-date alternatives for
that?
Many thanks,
Chiu

[PATCH] drm/nouveau: fix unknown chipset for GTX 1060
Nouveau driver shows unknown chipset (136000a1) for GTX 1060, so it
only gives VGA resolution on screen. Use the same chipset as nv134
then it shows FullHD. This commit copies fields from nv134_chipset
to nv136_chipset for GTX 1060.

Kernel panic on nouveau during boot on NVIDIA NV118 (GM108)
We are working with new desktop that have the NVIDIA NV118
chipset.
During boot, the display becomes unusable at the point where the
nouveau driver loads. We have reproduced on 4.8, 4.11 and linux
master (4.12-rc3).
Dmesg log is attached.
Is this a known issue? Anything we can do to help?
Thanks

[PATCH] drm/nouveau/core: recognise GP107 chipset
From: Chris Chiu <chiu at endlessm.com>
This new graphics card was failing to initialize with nouveau due to
an "unknown chipset" error.
Copy the GP106 configuration and rename for GP107/NV137. We don't
know for certain that this is fully correct, but brief desktop testing
suggests this is working fine.

[LLVMdev] name collision - llvm::tie and boost::tie
The BGL (Boost Graph Library) defines tie(), which is exactly what the
tie() defined in STLExtras.h.
The header files of GBL use boost::tie(), and other boost libraries
use boost::tie() too.
How to resolve the ambiguity for compiler?
