Hello Helpers, I have some problems with fitting the model for my data... -->my Literatur says (crawley testbook)= Non-normality of errors-->I get a banana shape Q-Q plot with opening of banana downwards Structure of data: origin wt pes gender 1 wild 5.35 147.0 male 2 wild 5.90 148.0 male 3 wild 6.00 156.0 male 4 wild 7.50 157.0 male 5 wild 5.90

Hi R-helpers, I was trying to put gender='Male' in newdata to create a expected survival curve for a pseudo cohort by using survfit based on Cox regression. My codes are shown below: fit<- coxph(Surv(end, status2)~gender, data=wlwsn1) Summary(fit) coef exp(coef) se(coef) z p genderMale 0.204 1.23 0.0912 2.23 0.025

Just a general question concerning the woolf test (package vcd), when we have stratified data (2x2 tables) and when the p.value of the woolf-test is below 0.05 then we assume that there is a heterogeneity and a common odds ratio cannot be computed? Does this mean that we have to try to add more stratification variables (stratify more) to make the woolf-test p.value insignificant? Also in the

Hello, I am currently using dovecot 2.0.13 and I have been working on keywords handling our webmail and I have a few questions about how dovecot handles them. First, if I am not mistaken keywords neeed to be UTF-7 encoded. That means I need to encode special caracters using values between & and - chars. UTF-7 encoding is case sensitive, &AOA- isn't the same chars as &aoa-.

Hello, I've upgraded our servers and now dovecot seems to be running out of memory when accessing my own mailbox (and only mine, which is in a way pretty fortunate): dovecot: imap(abelard-a): Error: mmap() failed with file /vmail/a/b/abelard-a/dovecot.index.cache: Cannot allocate memory imap(abelard-a): Fatal: pool_system_realloc(131072): Out of memory

Hi, I'm sure this is simple, but I haven't been able to find this in TFM, say I have some data in R like this (pasted here: http://pastebin.com/raw.php?i=sjS9Zkup): > head(df) gender age smokes disease Y 1 female 65 ever control 0.18 2 female 77 never control 0.12 3 male 40 state1 0.11 4 female 67 ever control 0.20 5 male 63 ever state1 0.16

Hi there I'm trying to fit a logistic regression model to data that looks very similar to the data in the sample below. I don't understand why I'm getting this error; none of the data are proportional and the weights are numeric values. Should I be concerned about the warning about non-integer successes in my binomial glm? If I should be, how do I go about addressing it? I'm

We run RANCID at the day job to back up switch and router configs. Version 3.11 adds some support for devices we need. The current EPEL version is 3.9. I filed a request at Fedora to get it updated, which they have completed (version 3.11), but it still hasn't made it into the EPEL for CentOS. What's the right place/process to get the update into EPEL for CentOS? All pointers

Hello, we are using dovecot 2.0.13 with maildir++ (we migrated away from courrier just a few months ago) and the RECENT status doesn't seem to be working: . STATUS INBOX (MESSAGES UNSEEN RECENT) * STATUS "INBOX" (MESSAGES 35106 RECENT 0 UNSEEN 10) then 2 minutes later: .

Hello I'm trying to keep my users from using the "redirect" action with pigeonhole from dovecot 2.0.21. As documented in http://wiki2.dovecot.org/Pigeonhole/Sieve/Configuration I configured sieve like this: plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_max_redirects = 0 } (and doveconf indeed shows the new setting for sieve_max_redirects) Unfortunately I

Hello, We have been using lda_mailbox_autocreate to avoid to intialize empty mailboxes upon account creations. This does the job allright except that dovecot-lda is also allowed to autocreate sub folders which is a problem when using addresses extensions (adress+folder at domain.tld). It's easy for a malicious user to flood a mailbox with tons of subfolders. Is there a way to tell

Whenever I use "..." in the formula of the cast function, from the reshape package, I get the following error: Error in `[.data.frame`(data, , variables, drop = FALSE) : undefined columns selected For example: data(french_fries) #available in the reshape package > head(french_fries) time treatment subject rep potato buttery grassy rancid painty 61 1 1 3 1

I have a data set that I'm trying to melt and cast in a specific way using the reshape package. (I'll use the ff_d dataset from reshape so I don't have to post a toy data set here. ) Lets say I'm looking for the interaction of treatment with each type of "variable" in ff_d. Using the command below gets me this. Subject will get a column and each treatment type by each

I looked for examples of count data that might interest the students and found this project about dropout rates in Los Angeles High Schools.

Hello, I have a question about glm: if i have a binary covariate (unit=1,0) the reference group would be 0?

Hi, being an off-topic questions with so many vendors involved I had no definitive place to go to ask but here. So maybe some of the list members have ideas in mind. Currently we manage several switches,firewalls and MS LDAP and Centos OpenLDAP installations. We are looking for a "man in the middle" or "framework" to manage change on our network devices and LDAP-based servers.
