...esterday. According to http://mirror-status.centos.org a whopping number of 227 mirrors are currently out of date. This is the major part of all European mirrors. :( Can someone please have a closer look at this? Thanks a lot and regards Patrick -- Lobster LOGsuite GmbH, Hauptstra?e 67, D-82327 Tutzing HRB 178831, Amtsgericht M?nchen Gesch?ftsf?hrer: Dr. Martin Fischer, Rolf Henrich

Dear R users, I am trying to fit a glm with a distribution free family, link = log and variance = constant*mu. I guess I have to use the quasi family but the choices of variance are restricted to constant or mu or mu^2..., I don't know the way to choose the variance that I need, i.e. constant*mu. If you have any ideas or advice, please tell me. Thanks, Laetitia Mestdagh Laetitia Mestdagh

Hello all, I am wondering if there is a way to do a spatial error probit/logit model in R? I can't seem to find it in any of the packages. I can do it in MATLAB with Gibbs sampling, but would like to confirm the results. Ideally I would like to use this model to predict probability of parcel conversion in a future time period. This seems especially difficult in a binary outcome model

How might you fit a generalized linear model (glm) with variance = mu+theta*mu^2 (where mu = mean of the exponential family random variable and theta is a parameter to be estimated)? This appears in Table 2.7 of Fahrmeir and Tutz (2001) Multivariate Statisticial Modeling Based on Generalized Linear Models, 2nd ed. (Springer, p. 60), where they compare "log-linear model fits to

Dear R-Users, without going into details I tried to prepare a simple example to show you where I would need help. In particular I prepare two examples-template for a study I'm conduction on discrete-time methods for survival analysis. Each of this example has two datasets which are basically equal, with the exception that in the former one has individual data and in the latter one aggregated

Dear R users, an update of the package ppls - Penalized Partial Least Squares - is now available on CRAN. It implements the methods described in N. Kr?mer, A.-L. Boulesteix, G.

Folks, Should semanage be part of the policycoreutils package? At least in 6.x, it's not. mark

We are happy to announce that the second R user conference useR! 2006 is scheduled for June 15-17 2006 and will take place at the Vienna University of Economics and Business Administration. This second world-meeting of the R user community will focus on - R as the `lingua franca' of data analysis and statistical computing, - providing a platform for R users to

Dear R-listers, I am working with generalized linear mixed models to quantify the variance due to two nested random factors, but have hit a snag in the interpretation of variance components. Despite my best efforts with Venables & Ripley 2002, Fahrmeir & Tutz 2001, R-help archives, Google, and other eminent sources (i.e. local R gurus), I have not been able to find a definitive answer
