Hi I have some panel data for the 50 US states over about 25 years, and I would like to test a simple model via OLS, using this data. I know how to run OLS in R, and I think I can see how to create Panel Corrected Standard Errors using http://jackman.stanford.edu/classes/350C/pcse.r What I can't figure out is how to correct for autocorrelation over time. I have found a lot of R stuff on time series models but they all seem focused on predicting a single variable from its previous values. Can anyone explain to me how to detect and get round...

Hello, I am considering giving a talk at my university on R to (mostly) academics. There wouldn't be any statisticians, but professors from mathematics, psychology, economics, etc. who do use some statistical software in teaching and/or research, and have an acquaintance with procedures and graphics used in statistics. Has anyone given such a talk to a similar audience? If so, I would be

...for a Poisson or negative-binomial model. Since the focus of your paper is the methodology, you might want to try a zero-inflated Poisson or negative-binomial model. Though I haven't tried them, I'm aware of two sources of R functions for zero-inflated count models -- zeroinfl(), from Simon Jackman's web site <http://pscl.stanford.edu/content.html>, and gnlr() in Jim Lindsey's gnlm package, which is not available on CRAN but at <www.luc.ac.be/~jlindsey/rcode.html>. >>> Indeed. I am going to use these, as well, and attempt to demonstrate that fitting the correct m...

Hi, I have two questions. First, I'd like to compare a ZINB model to a negativ binomial model with the Vuong test, but I can't find how to performe it from the zicount package. Does a programm exist to do it ? Second, I'd like to know in which cases we have to use a double hurdle model instead of a zero inflated model. Many thanks, St??phanie Payet REES France R??seau

...gular volume, and may not fill up completely. Volume 24 is 'Statistical Modeling of Social Networks with "statnet"' -- it is not a Foometrics volume but can serve as another model for special volumes. Another Foometrics volume (Political Methodology in R, guest editors Altman and Jackman) will be out early 2008. If you have suggestions about special volumes of either type ("Foometrics with R" or "Statistical modeling of X with R/Stata/SAS/... package Y" or "Statistical modeling of X with R/Stata/SAS/...") drop me an email.

...a zip ( zero excess coming from a "mixture") or a negBin (zero execess due to overdispersion) model. Of course some likelihood based criteria (eg AIC) could be of help for you However it is possible (at least in principle) to account for both extra zeros and overdispersion as well. S. Jackman has written code to fit zip or zinb regression models http://pscl.stanford.edu/zeroinfl.r You should modify the code if you want to assume different "linear predictors" in the logit (zero vs non/zero) and count part Hope this helps, vito Seyed Reza Jafarzadeh wrote: > Dear list,...

Hello I am interested in Poisson or (ideally) Negative Binomial regression with an inflated number of 1 responses I have seen JK Lindsey's fmr function in the gnlm library, which fits zero inflated Poisson (ZIP) or zero inflated negative binomial regression, but the help file states that for ' Poisson or related distributions the mixture involves the zero category'. I had thought

Dear list, I would like to fit a negative binomial regression model as described in "Byers AL, Allore H, Gill TM, Peduzzi PN., Application of negative binomial modeling for discrete outcomes: a case study in aging research. J Clin Epidemiol. 2003 Jun;56(6):559-64" to my data in which the response is count data. There are also 10 predictors that are count data, and I have also 3

Dear R-users, There are tons of methods out there for fitting independant variables to a dependent variable. All stats books tell you about the assumptions behind OLS (ordinary least squares) and warn against abusive use of the method (which many of us do disregard by lack of a better knowledge). Most introductory text books stop there and don't tell you what the next best option might be. I
