nls() vs lm() estimates
Hi,
I'm trying to understand why the coefficients "a" and "b" for the model: W = a*L^b estimated
via nls() differs from those obtained for the log transformed model: log(W) = log(a) + b*log(L)
estimated via lm(). Also, if I didn't make a mistake, R-squared suggests a "better" adjustment
for the model using coefficients estimated by lm() . Perhaps I'm

suspected bug in dovecot-ldap setup?
Hi everyone,
[first post: long and boring. beware!]
I've been working on a virtual multidomain MX server with pop3 access.
Accounting for users/domains is done via OpenLDAP with the Jamm[1] schema and
dovecot is 1.0rc10 (dovecot-1.0-0_27.rc10.el4.at fetched as RPM from
atrpms.net for CentOS 4.4).
I intended to have authenticated binds but there was a problem with the

Protocol 2 remote port forwarding
Hi all,
I'm using openssh-2.9p2 on Solaris 2.8. I can get remote port forwarding to
work using the -R flag, but only with ssh protocol 1 not ssh protocol 2.
I've read that remote forwarding protocol 2 was not supported in earlier
versions of openssh, but I'm wondering if this is still the case. Jarno

Strange read_passphrase behaviour ?
Hi,
I'm sorry if this has already come up on the list, I did a quick search
of the archive and didn't notice it.
I noticed IMHO strange behavior in read_passphrase:
If readpassphrase returns NULL and sets errno to ENOTTY, then
read_passphrase returns an empty passphrase to the caller instead of
error, now what happens with password authentication is that
if readpassphrase fails every

Syslog facility in Linux
Hi !
While browsing Linux manpages (man 3 syslog) I noticed that the manual
says that the LOG_AUTH facility is deprecated use LOG_AUTHPRIV instead.
Is there a good reason why OpenSSH doesn't have an option to use
LOG_AUTHPRIV facility ? (Looks like that tcpd/telnet etc. use the AUTHPRIV
facility (in RH6.2)).
Shouldn't be too hard to add the AUTH_PRIV facility ?
Cheers,

Error message in function mars() in package mda
Hi,
I am using function mars() in package mda to find knots in a whole bunch
of predictor variables. I hope to be able to replicate all or some of
the basis functions that the MARS software from Salford Systems creates.
When I ran mars() on a small dataset, I was able to get the knots.
However, when I tried running mars() on a larger dataset (145 predictor
variables), for a different

[PATCH] Ignore unfragmented file checks in defrag when compression enabled
I noticed that btrfs fi defrag -c<method> can''t be used to compress files
unless they are fragmented. This patch corrects the problem, by informing
should_defrag_range if compression is enabled, and skipping tests for extent
and adjacent extents if it is.

Need help in waveslim package: imodwt and universal.thresh.modwt
Hi:
I have encountered problems with imodwt and universal.thresh.modwt and cannot find any reference in R Search. Hope someone can give me some ideas:
Starting with
modwt.la8 <- modwt(xdata, "la8", n.level=6) <-- this seems to work fine
(1) ydata <- imodwt(modwt.la8)
will always give ydata as numeric(0) (no values) instead of being a time series data with

polychoric correlation error
Dear all,
I get a strange error when I find polychoric correlations with the ML method, which I have been able to reproduce using randomly-generated data.
What is wrong?
I realize that the data that I generated randomly is a bit strange, but it is the only way that I duplicate the error message.
