similar to: Predicted values when using offset in ZIP GLM

Hi all- I fit a zero-inflated Poisson model to model bycatch rates using an offset term for effort. I need to apply the fitted model to a datasets of varying levels of effort to predict the associated levels of bycatch. I am seeking assistance as to the correct way to code this. Thanks in advance!

Hello, I am researching using dovecot with an SQL database as the storage backend. From what I've read, dovecot only supports mbox style file storage, but I'd like to investigate the possibility of using a database instead. According to http://dovecot.org/pipermail/dovecot/2006-June/013818.html, this possibility has been explored before and has generally been accepted that Dovecot

I'm reporting a problem with documentation for openssh 3.7 portable. In the INSTALL file it says in the configure section: --with-md5-passwords will enable the use of MD5 passwords. Enable this if your operating system uses MD5 passwords without using PAM. The above verbage implies that if you use PAM there's no need to use the --with-md5-passwords option. This, I have discovered, is

Hi all, I know some may find this OT, so please ignore this if you think it's OT. I don't know any Linux-friendly Windows mailing lists / forums that will even bother with Linux related questions. I want to carry some data (client info, documents, photos, email, accounting stuff, etc) with me on a USB HDD, but want to encrypt it. I know one easy way to shared data between Windows &

Hello everyone, Is it possible to, from one instance, bind a single userdb to a specific listen port in Dovecot? For example, requiring passwd or PAM authentication on IMAP port 143, but using an SQL passdb only on port 8143?

I'm used to Debian-based distros which have a tempfile(1) utility for safely and sanely creating temporary files. There isn't a comperable utility for RHEL/CentOS systems. I've been exercising Google-fu looking for a good robust tempfile generation idiom, but haven't turned one up yet. Hence this appeal to the lazyweb. -- Dr. Ed Morbius, Chief Scientist / | Robot

Hi all, I wrote shell script and put it under the /usr/local/bin/ directory. I use echo $0 for get script name but it has printed "/usr/local/bin/<scriptname>" but i want to only print <scriptname> How can i do this ? Thanks all for help. -- Iyi calismalar.Basarilar...

Hey Guys, I can not find the corrent syntax for what I am trying to acheive with a while loop. Having said that I'm not exactly sure what you would call it so I have been googling with no success probably for that reason. I am just working with some sub directories except there is one I don't want to use so I have a while loop like the following; if we stubmle into the sub directory I

Hey Listees, I have a question (hopefully quite simple) about the system V init scripts in /etc/init.d. I have an app installed and for some reason it had no system V init script. It has been installed a long while now so I can't quite remember whats going on but basically I remember I wrote the init script my self and the app is enabled as a service which chkconfig to run at system levels 3,

Hi, Despite the mailing list and twitter I did not find any updated info on either versions regarding the current status. So, what is the current status of both versions?

I won't bother quoting all of Moz's statements of how sound is interpreted by those blessed/cursed with tape recorders in their heads :) I will add that his whole explanation of perfect pitch perception easily offers an explanation as to why some individuals will only archive flac/pac/ape (Moz - do you?) and those of us that do not perceive that level of detail and are fine using ogg

Hi All, I need to write a script that I will manually start (or a cron job in future) but I need it to do a number of things in order one after another. How do i do that so everything gets dont as the steps depend on each other. Example: cd /system_backups/ tar cvf apache-conf.tar /etc/httpd/conf/* gzip -v9 apache-conf.tar tar cvf apache-data.tar /var/www/* gzip -v9 apache-data.tar

Dear R helpers, running the following code of a glm model of the family poisson, gives predicted values < 0. Why? library(MASS) library(stats) library(mvtnorm) library(pscl) data(bioChemists) poisson_glm <- glm(art ~ fem + mar + kid5 + phd + ment, data = bioChemists, family = poisson) predicted.values = predict(poisson_glm) range(predicted.values) Thank you in advance for any hints.

Guys, apache cpus usage is hitting 100% sometimes ( to such an extent that its very noticeable) on a box with just 8 users or so. i m getting this when i run 'top'.

Hi, I am trying to figure out the observed acceptance rate and M, using generalised rejection sampling to generate a sample from the posterior distribution for p. I have been told my code doesn't work because I need to "take the log of the expression for M, evaluate it and then exponentiate the result." This is because R is unable to calculate high powers such as 545.501. As

Hello, I've got a small dataset on box turtle shell measurements that I would like to perform a detrended correspondence analysis on. I thought that it would be interesting to examine the morphometrics for each species in the area of overlap and in areas where neither species occurs.  I've taken a look at the dune and dune.env datasets in vegan. Using the str() command gives me  >

## the following is a dream: add some sugar syntax to allow for contracts with teeth (in and out checking) > is.positive <- function(x) (all(x>0)) > exponentiate <- function( x ::is.data.frame , exponent ::is.numeric is.positive) :: is.vector is.numeric { x$base :: is.positive ## error also if base does not exist in x; may need some special IQ x$base^exponent }

Dear R community, Is this sample size large enough to study differences between two groups of the populations? Q1: do the body temperatures differ between the two groups of the overwintering turtles juveniles and adults? One group (adults) has 6 turtles Second group (juveniles) has 1 turtle. There are 3 replications, i.e. the experiment was repeated over the three years, but using

Suppose I have a square matrix P P <- matrix(c(.3,.7, .7, .3), ncol=2) I know that > P * P Returns the element by element product, whereas > P%*%P Returns the matrix product. Now, P^2 also returns the element by element product. But, is there a slick way to write P %*% P %*% P Obviously, P^3 does not return the result I expect. Thanks, Harold [[alternative HTML version

Dear R community, I am wondering what experimental design I am dealing with? I study the effect of daily air temperature on daily body temperature of the overwintering turtles (i.e. sleeping in soil). The model is a cosine wave with the air temperature as a covariate. Objects are 19 overwintering turtles. Data were combined over the three years. Each turtle was studied only once during these
