Kolmogorow-Smirnow-Test to check if Data comes from Subbotin distribution
Hi,
I have a Data Set x and I want to check with a Kolmogorow-Smirnow-Test, if x comes from a Subbotin Distribution, whose density function is:
function(x,location,scale,tail) # Exponential power (=Subbotin)
{
const<- 2*scale*tail^(1/tail) *gamma(1+1/tail)
z<- (x-location)/scale
exp(-1/tail*abs(z)^tail)/const
}
How can i do this? Thank you

sievec fails when last line is a comment without trailing \n
Hi,
when switching from Dovecot 1.1 + cmusieve to Dovecot 1.2 + sieve
I stumbled upon the following problem:
My sieve files, generated with Dovecot 1.1's managesieve, did not
compile anymore with sieve's sievec.
The error message was:
error: end of file before end of hash comment.
Looking a bit closer I found that the last line, which was a comment,
did not have a trailing newline.

Samba on Linux with no ACL's is making things tough
Please for give me if this gets a bit long.
I am presently in the process of moving my company's file server from
Windows NT 4.0 over to Linux with SAMBA and the lack of ACL support in
the ext2 filesystem is making things very difficult to design. To
clarify I am NOT writing about Samba's support for NT ACL's on NTFS. I
am writing to possibly get some tips for getting around the lack

deletion of symlinks from Windows Clients
All,
I would like to use symlinks to give my users access to all folders they
need right from their home directory. I create the symlinks as root and
they cannot delete the symlink in their home directory from windows.
However when they try to delete the folder (ie highlight it and hit the
delete key from windows) the contents of the folder is deleteable (if
they have write access to the folder)

R example of Mahalanobis, Kolmogrov, ROC, Gini, Delta
Dear R helpers:
I have another question regarding "R" command. It is also measuring Credit
Scoring.
I need to measure the classifying method for customer's credit score. (ex.
regression line by Fisher)
If credit card company already classify their customers credit :
Good customers / Bad customers
[by using regression line; ex) inside of line: Good/ outside: Bad]
And I found

Do I get some help?
Dear helper.
I am a student in SFSU.
I had a class that introduce a new open-source "R" in this semester.
It's, however, hard to understand how to make "R" command.
Especially, at this time we( including my friend) have to explain some
concepts
(e.g. mahalanobis distance, kolmogorov-smirnow statistics, ROC curve, Gini
coefficient, and the delta approach)
We have to

Deploying geo-replication to local peer
Hi Kotresh,
Thanks for response!
After taking more tests with this specific geo-replication configuration I realized that
file extended attributes trusted.gfid and trusted.gfid2path.*** are synced as well during geo replication.
I?m concern about attribute trusted.gfid because value of the attribute has to be unique for glusterfs cluster.
But this is not a case in my tests. File on

[Linux] Samba as Wins Server and Domain Controller
As much as I love Samba, OpenSores, Linux and apple pie, setting Samba as an
NT domain controller used to be a bit of a hack that required a lot of shoe
horning, and a lot of reading, and experimentation.
Get the books, sign up for the support email list and be prepared for a
bumpy ride.
The problem is that certain things *should* work a certain way, but such is
not always the case and you

Equivalents of Matlab's 'find' and 'end'
Sorry if these questions have been asked recently--I'm new to this list.
I'm primarily a Matlab user who is attempting to learn R and I'm searching for possible equivalents of commands that I found very handy in Matlab. So that I don't seem ungrateful to those who may answer, I HAVE determined ways to carry out these processes in 'brute force' sorts of ways in R code,

Testing sharding on tiered volume
Hi,
I'm looking to use sharding on tiered volume. This is very attractive
feature that could benefit tiered volume to let it handle larger files
without hitting the "out of (hot)space problem".
I decided to set test configuration on GlusterFS 3.12.3 when tiered volume
has 2TB cold and 1GB hot segments. Shard size is set to be 16MB.
For testing 100GB files are used. It seems writes

Deploying geo-replication to local peer
Hi,
I'm looking for glusterfs feature that can be used to transform data between
volumes of different types provisioned on the same nodes.
It could be, for example, transformation from disperse to distributed
volume.
The possible option is to invoke geo-replication between volumes. It seems
is works properly.
But I'm concern about requirement from Administration Guide for Red Hat

2D Kolmogorov-Smirnov test: solution
Hi - A little while ago I posted a question about the implementation of
a two-dimensional analog of the Kolmogorov-Smirnov test in R[1][2]. As
there isn't one, as far as I know, people might be interested in a very
fast C++ implementation called MUAC which is available as a function
and as a standalone program from
http://www.acooke.org/jara/muac/index.html. Apparently the code is

apparently incorrect p-values from 2-sided Kolmogorov-Smirnov (PR#14158)
I've fixed this by adding 0.5/mn to q. The problem (at least in principle) with multiplying them all up is integer overflow.
By the time 0.5/mn underflows to zero, missing one value in the distribution won't matter.

apparently incorrect p-values from 2-sided Kolmogorov-Smirnov (PR#14157)
Dear Thomas, Right, thank you. Yes, I haven't looked at the source code
(because I don't know C) but something like what you mention could
well cause the kind of problems I am seeing: a loop being exectued one too
few or one too many times. And yes, I think those quantities should be
multiplied up by m*n to all become integers so we escape rounding error
problems. David.

apparently incorrect p-values from 2-sided Kolmogorov-Smirnov (PR#14178)
Dear Thomas, Thank you, yes, that sounds good, and I take the point about
integer overflow.
Various questions:
(a) Is there some way I can try out the routine with this modification? (I
am on a Linux system where I am just a user - I cannot install new
versions of software myself) ?
(b) Is there a reference you can give me to a published paper where the

modified kolmogorov-smirnov
I'm trying to use modified Kolmogorov-Smirnov test with a Normal which I
don't know it's parameters. Somebody told me about the lilifor function in
R, but just can't find it.
Does anybody know how I can test with the modified Kolmogorov-Smirnov
test?

kolmogorov-smirnov
Hello,
I got a rather simple question: Can I find somewhere in R the
significance values for a Kolmogorov distribution (I know the degrees
of freedom and I have already the maximum deviation). ks.test is not
really doing what I want. All I need is the values, like one can get
the values for a chi-squared distribution by 'qchisq(0.05, 375)'.
tnx,
Kurt.

kolmogorov-smirnov for discrete ordinal scale data
Hi,
I was wondering whether there is an implementation of the
Kolmogorov-Smirnov goodness of fit test for discrete, ordinal scale data
in R - I've only managed to find the test for continuous data.
Thanks!
