Convergence warnings from zeroinfl (package pscl)
Dear R-Helpers, Can anyone please help me to interpret warning messages from zeroinfl (package pscl) while fitting a zero inflated negative binomial model? The console reports convergence and the parameters seam reasonable, but these <<Warning messages: 1: algorithm did not converge in: glm.fit(X, Y, family = poisson()) 2: fitted rates numerically 0 occurred in: glm.fit(X, Y, family =

Zero inflated Models- pscl package
Dear R users, I want to apply zero inflated models with continuous and categorical variables and I used pscl package from R and the zeroinf() function. My question are the follow: a) The value of fitted.values is mu or (1-p)*mu? where p is the probability of zero came form a zero point mass b) If mu is zero, how do i know if it is a zero from the zero point mass or from the count process?

AIC on GLMM pscl package
Hello, I'm using GLMM on the pscl package and i'm not getting the AIC on the summary. The code i'm using is (example) : mmall3 <-glmmPQL(allclues ~ cycloc + male, data=dados, family=poisson, random=~1|animal/idfid) and the results: Linear mixed-effects model fit by maximum likelihood Data: dados AIC BIC logLik NA NA NA Random effects: Formula: ~1 | animal

R not finding function in installed pscl package
Hi, This may be such a general question that my searches are just failing. I installed the pscl lib, all appears fine, installed it several different ways to be sure, but I am getting: Error: could not find function "zeroinfl" I double checked my spelling of the function and that it had not been evolved out of the package. It is in the same location as the other libraries that are

Zero-inflated neg.bin. model and pscl package
Dear list, I'm currently trying to develop a model to assess clam yield potential in a lagoon. I'm using the zeroinfl function of the pscl package to fit a Zero-inflated negative binomial model, given the high occurrence of zero counts. I don't understand from the sentence in the pscl guide "Zero-inflated count models are a type of two-component mixture model, with a component

fitted.values from zeroinfl (pscl package)
Hello all: I have a question regarding the fitted.values returned from the zeroinfl() function. The values seem to be nearly identical to those fitted.values returned by the ordinary glm(). Why is this, shouldn't they be more "zero-inflated"? I construct a zero-inflated series of counts, called Y, like so: b= as.vector(c(1.5, -2)) g= as.vector(c(-3, 1)) x <- runif(100) # x

Zero inflation model - pscl package
I have some questions regarding Zero Inflation Poisson models. I am using count data to analyze abundance trends of salamanders. However, I have surveys which differ in the amount of effort (i.e. the number of people searching and amount of time - I am using a museum database so not all surveys were conducted by me). Therefore I need to account for the effort. If change the count (response

What would the ideal server setup be?
I have one dedicated server for all my various projects (both PHP as well as Rails) and will be getting a second server to run only the Rails apps on. What is the ideal server setup in terms of RAM vs. Processor Speed (more RAM or more processor speed?) and should I use Apace, lighttpd, mongrel, or what? I''ve got the money to afford something pretty solid...just don''t know

how to calculate the ideal value for client.event-threads, server.event-threads and performance.io-thread-count?
Defaults should be fine in your size. In big clusters I usually set event-threads to 4.

[LLVMdev] Ideal way to build llvm and friends?
Hi all, I'm a maintainer for the llvm ecosystem for nixpkgs[1]. Currently only clang and llvm are up-to-date, but I'd like to move to building all of the packages listed on the release page for the latest version (and in particular, have libc++ and compiler RT integrated in with llvm/clang). Right now we're using the CMake build, with llvm and clang being built as separate

Ideal RAID-1 Stripe Size for IMAP Server ?
Hi there. I'm currently configuring a brand new email server(IMAP) which will run CentOS 6.3 x64. So lots of files on the data volume. I'm confused about stripe size for my data volume. I'm using 2x500GB for OS in RAID1 and 2x2TB SAS for DATA in RAID1 which is hosted on a HP Smart Array P420 Controller with 1GB in Cache/Battery Backed Up. Both these array's are on the P420

Ideal number of clusters using the Fanny algorithm
Hello, Could someone please let me know the procedure for determining the 'best' solution with regards to the number of clusters using the Fanny algorithm for computing fuzzy clusters? The function requires a specification of the number of clusters a priori, but I am interested in determining what number of clusters would result in the ideal fit with the data. Any help/advice/pointers to

Ideal (possible) configuration for an exalted R system
Hi All, I am trying to assemble a system that will allow me to work with large datasets (45-50 million rows, 300-400 columns) possibly amounting to 10GB + in size. I am aware that R 64 bit implementations on Linux boxes are suitable for such an exercise but I am looking for configurations that R users out there may have used in creating a high-end R system. Due to a lot of apprehensions that SAS

Ideal Setup for T1/PRI and TE110P - second try
Hi all, I'm sure something similar has been discussed, but one can only wade through the archives for so long. I'm setting up a T1 and my telco has a bunch of questions it wants me to answer. I know much of the TE110p is configurable to do any of this, but I wanted to know if there is an optimal or preferred setup. Any help would be appreciated. Here is the quiz my telco is giving me:

pscl package and hurdle model marginal effects
This request is related to the following post from last year: https://stat.ethz.ch/pipermail/r-help/2011-June/279752.html After reading the thread, the idea is still not clear. I have fitted a model using HURDLE from the PSCL package. I am trying to get marginal effects / slopes by multiplying the coefficients by the mean of the marginal effects (I think this is right). To my understanding, this
