similar to: writing an MDA, help me avoid corrupted indexes

For a private package ("soon" to be on CRAN), I started looking at and thinking about the function confusion() from the mda package and wondered if it wouldn't make sense to provide the generic function in base R and also think about making the default for the `true' argument equal to fitted(object). One could write methods for confusion() for almost all classifiers which

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

Dear helpers, I am trying to use the mda package downloaded from the R website, but the data set has missing values so I got an error message. Should I manually handle these missing values? I was trying to read the documents to specify any option related to missing values, but I did not find it. Please forgive me if I ignore something obvious. Thanks, Zhu Wang Statistical Science Department

Hi all, I'm at the stage of planning our new mail system and am evaluating dovecot for it. For large mailstore setups, it makes sense to split maildirs across many directories. I see that setting default_mail_env to something like maildir:/var/imap/domain/%1d/%d/%1u/user/%u/ would create almost identical on-disk layout as multidomain cyrus setup. Now, as dovecot does not have its own

Dear list! I'd like to know if some- one has experience with system running no mta (aka sendmail). I have single comp, not server, not lan. Yes! Sendmail is nice, but it is too big for simple tasks I have for it. My intention is to use apps small as possible. This letter gone from mutt directly to ssmtp, that processed it to my isp. (Setting option for sendmail as

Hello...I'll TRY make this short. This post is not specific to Dovecot...but many subscribers to this list have probably been down this road. (private replies welcome if you want it to go off list) I currently use Sendmail with MailScanner, SpamAssassin, ClamAV, Procmail, and qpopper for POP3 (hash mail dirs for mbox files)on RedHat 9 server. Roaming users currently only have the option of

Hello, I am using the function mda of the mda library in order to discriminate 4 groups with 8 explanatory variables. I only have 66 observations. I tested all possible combinations of those variable and run for each the Mixture Discriminant Analysis. For some iterations, I got an error message: "error in kmeans(xx, start): initial centers are not distinct". I understood that the

Hello, I currently have one machine running postfix SMTP server as MTA along with dovecot IMAP server for email. Although it only supports a handful of users, email service is important to us all; so I'm looking to make this a more fault-tolerant / highly-available system. To that end, I'm planning on configuring postfix to use deliver/dovecot-lda as my MDA (using procmail at the

Hello, I'm preparing to convert from qpopper + UW-IMAP to dovecot. So far testing has gone very well. One problem we haven't figured out is that long-running POP sessions keep the mailbox locked, so that the MDA times out while trying to deliver. We're using "maildrop" as our MDA if that matters. We don't see this issue for dovecot IMAP sessions. During long-running

Hi, I have some trouble to use dovecot as MDA. I followed the instructions in http://wiki.dovecot.org/LDA and http://wiki.dovecot.org/LDA/Postfix I have multiple virtual users, stored in a LDAP server, and it look like postfix is still delivering the mails directly to the maildirs. Dovecot version : 1.2.15 (using the 1:1.2.15-4 squeeze packets) postfix version : 2.7.1 (using the 2.7.1-1

Hi, I''m currently thinking of writing my bachelorthesis about the use of model driven architecture within webdevelopment. I''m now trying to figure out about the benefits of using MDA to generate Rails Code. So, which Components of an Web-/Rails App would you like to be generated via MDA? In which way do you think the generators shipped with Rails can be improved? -- Posted via

Hi all, Has anyone tried to do k-fold cross validation for flexible discriminant analysis ( mda library), for example, using crossval() in bootstrap? The problem is that the function crossval() requires a separate matrix for predictors and another for responses, whereas the function fda(), using the formula argument only. Is there another way of doing k-fold cross validation for functions which

NEW: CRAN/src/contrib/devel/mda_0.1-1.tar.gz I have made a first shot at porting the Hastie & Tibshirani mda package t= o R ... this is almost not tested at all ... but it works for the iris data and what else could a statistician be possibly interested in anyway = :-) All BRUTO stuff is missing because there are some unresolved symbols: R.binary: can't resolve symbol

Hello all, So I'm doing some data analysis using MARS. I have a matrix of 65 independent variables, from which I'm trying to predict 71 dependent variables. I have 900+ data points (so a 900x136 matrix of data), which I randomly split into training and validation sets, for ~450 data points in each set. Occasionally, this works well, and I get decent predictions. However, quite often

hmm if message cannot be written to disk surely it remains on mda queue as not delviered and does not just disappear ? or am i reading this wrong ?! > Dag Nygren <mailto:dag at newtech.fi> > 16 August 2017 at 7:14 am > Thanks for all the advice on how to configure systemd > not to loose my emails after every update.

Hi folks, I am currently evaluating Dovecot for deployment to ~200 software engineers (so, heavy email users); I'm hoping this list could provide wisdom about how best to do the configuration, evaluation and deployment, and what testing folks have done to determine whether dovecot is right for their site. Below I've listed the diffs between the dovecot-example.conf and our config.

On RHEL5, dovecot 1.0.7, I have set up sendmail to use `deliver` for my local mda. It keeps giving me this error for the root user though: Jul 12 12:51:29 mail sendmail[4105]: o699225f001348: to=<root at localhost.localdomain>, ctladdr=<root at localhost.localdomain> (0/0), delay=3+08:49:26, xdelay=00:00:00, mailer=local, pri=7502879, dsn=4.0.0, stat=Deferred: local mailer

I have spent a long time looking into this and can't find the answer I'm looking for, so I'm asking here. I'm cutting the example down to just the bare minimums. This is NOT my actual configuration, but is sufficient for asking this question: How can I use dovecot's deliver LDA to deliver to virtual users, but then have unknown virtual users fall back to catch-all
