Hello, I''m going to be helping a friend setup Shorewall in place of his Cisco router on his home network. Shorewall will be acting as the router/firewall gateway for internet access for his home LAN. His connection to the ISP is via PPPOE. Nothing unfamiliar here to me. It will be a standard 2 interface setup. My curiosity was peaked when he said that he is going to be installing

I?m trying to spec a ?binary?, and as previously discussed on this list, I?m trying to do it ?from outside? ? i.e., by calling it with Kernel#` and observing the (side-)effects. Unfortunately, this doesn?t really let me spec expectations about its internals. Let?s assume I have a -d flag and I parse it with Trollop to set Conf.debug: opts = Trollop::options do opt :debug, ''Print debug

Hi! I''m observing some problems using gem inside Rails. My understanding is that after following sequence in irb: $ irb irb(main):001:0> require ''rubygems'' => true irb(main):002:0> require ''active_record'' => true irb(main):003:0> gem ''acts_as_taggable'' => true I should have access to acts_as_tagable mixins, like:

Dear R - help, I am working on the Credit scorecard model. I am using the Logistic regression to arrive at the regression coefficients model. I want to use the Hosmer - Lemeshow test . In order to understand the use of R - language, I had referred the following URL       http://www.stat.sc.edu/~hitchcock/diseaseoutbreakRexample704.txt The related data 'diseaseoutbreak' is available

I'm trying to do a Hosmer-Lemeshow 'goodness of fit' test on my logistic regression model. I found some code here: http://sas-and-r.blogspot.com/2010/09/example-87-hosmer-and-lemeshow-goodness.html The R code is above is a little complicated for me but I'm having trouble with my answer: Hosmer-Lemeshow: p=0.6163585 le Cessie and Houwelingen test (Design library): p=0.2843620

I know that there are two method to apply the Hosmer and Lemeshow?s. One of them is calculated based on the fixed and pre-determined cut-off points of the estimated probability of success. One of them is calculated based on the percentiles of estimated probabilities. In the previous post,i find that the Hosmer and Lemeshow?s test how to use in R. hosmerlem <- function (y, yhat, g = 10) {

i want to know how to use the Hosmer?Lemeshow test? in R. Can anyone show me the program to me and tell me how to use it? -- View this message in context: http://www.nabble.com/HOW-to-use-the-Hosmer%E2%80%93Lemeshow-test%E2%80%8F-in-R-tp19675283p19675283.html Sent from the R help mailing list archive at Nabble.com.

I haven't find any helpful thread. How can i calculate BIC and Hosmer-Lemeshow statistic for a logistic regression model. I have used glm for logistic fit. -- View this message in context: http://www.nabble.com/BIC-and-Hosmer-Lemeshow-statistic-for-logistic-regression-tf3945943.html#a11193273 Sent from the R help mailing list archive at Nabble.com.

I'am having a rare situation with ssl connections. I can connect to 993/995 but the connection never starts. >From the client side i test with: $ openssl s_client -connect example.com:993 CONNECTED(00000003) and stays like that... waiting. In the other side i see in dovecot logs: Disconnected: Inactivity (no auth attempts): rip=x.x.x.x, lip=x.x.x.x, TLS handshaking this happens from

I have a 1945 Bottle of Vintage Port Specially Bottled for the President, Richard M. Nixon. I have a picture, just don't know how to post it on this forum. The label says Borges&Irmao and from Portugal. Any idea what this is worth?

I have several too and I also see this problem on occasion. Like you say, it is fairly rare and I can't pinpoint a cause or tell if it is a symptom of something else. I think I wrote to tech support about it but never heard anything. I'm wondering how long they will continue to support the phone. -Nate > -----Original Message----- > From: Jerry Geis

We've been running 1.1 rc3 now for about a month, and overall it's been very fast and stable. There is however an Index-related problem that keeps cropping up which prevents a user from accessing their mailbox until their Indexes are manually removed. Somehow, an Index becomes problematic, and Dovecot hangs forever when the mailbox is accessed. It manifests when a user logs in and

Hello, I am a Samba user, and I have been using long time without any big trouble. Last week I was working with a friend, using Fedora and Samba 3. Excuse me, I don't know exactly which Samba version. After some problems, we shared a directory (for example, /data). This works, fine. Then we created two new subdirectories: /data/a /data/b Then we access to shared resource using smbclient,

I have a data frame with some factor columns. I want to drop the rows with rare factor values (and remove the factor values from the factors). E.g., frame$MyFactor takes values A 1,000 times, B 2,000 times, C 30 times and D 4 times. I want to remove all rows which assume rare values (<1%), i.e., C and D. i.e., frame <- frame[[! (frame$MyFactor %in% c("A","B"))]] except

I'm running a rare events logit model in R using the Zelig package and am getting some of the oddest error messages that I can't figure out. y = rnorm(100) x = c(rep("0",1), rep("1",99)) d = data.frame(won=x, bid=y) d mod1 <- zelig(y~x, model="relogit", data=d, tau=1/100, case.correct="prior", bias.correct=TRUE, robust=TRUE) > mod1 <-

Hi all, If I start two o more connections with diferent users that make a search text to solr I get this message many times: Error: fts_solr: Query didn't return uid If I repeat the test about 2000 times, with only one user concurrent, with 60 diferent users, without concurrent, I get between 0. If I repeat the test about 2000 times, with 2 users concurrent, I get between 3 or 10 errors.

dear all, i made some analysis with logistic regression. do you know if there is already a function available for the hosmer-lemeshow fitness test? thank you very much for the help best wishes andi
