question of plm package
Dear R help, I use the package plm the function plm() to analyse a panel data and estimate a fixeffect model. I use the code as follow : fe <- plm(y~x+z, data, model = "within") I want to use bootstrap to estimate standard error I consult the paper plm.pdf , but I can't find any answer. Can I estimate variance with bootstrap? Thanks, Helen

So I use the code the that is posted in the following link: http://www.econ.uiuc.edu/~roger/research/panel/rq.fit.panel.R How to estimate the panel data quantile regression if the regression contains no constant term?

Sample or Probability Weights in LM4, NLME (and PLM) package
Dear all, First, I would like to thank you for your immense work. My question is about a frequent topic which I am not able to solve - even after hours of search in the mailing lisy. I would like to analyse random-effects (and fixed-effects)models of longitudinal / panel data with sampling weights. I have an unbalanced panel of different individuals in 5 years and income data as well as their

plm: plm.data vs pdata.frame
Hello, I am trying to use the plm package for panel econometrics. I am just trying to get started and load my data. It seems from most of the sample documentation that I need to use the pdata.frame function to get my data loaded. However, even after installing the "plm" package, my R installation cannot find the function. I am trying to follow the example in plmEN.pdf (

anova for plm objects
Dear All, I'm looking to perform an ANOVA between two nested panel fixed effects models. I tried with anova, as well as with waldtest. anova tells me there is no method available for plm objects, while waldtest tells me my models are not nested. I think they are instead. The difference between the two models is that in the second I let the regression coefficients of a given variable variate

trouble switching to 'plm' from 'xtabond' and Stata
Hello, I am switching to R from Stata and I am having particular trouble with the transition from Stata's 'xtabond' and 'ivreg' commands to the "plm" package. I am trying to replicate some of the dynamic panel data work using the UK Employment data in Arellano and Bond (1991) and available as 'EmplUK' under the 'plm' package. I have been

R: Problems using log() in a plm() regression.
Hello. Just a quick follow-up, for other 'plm' users on the list: - the problem turned out to be logs of zero values hidden in the big dataset - trying log(xx) would not reveal the problem, because log(0)=-Inf is a valid result in log() while it is an invalid input to plm() --> it is always advisable to try lm(yourformula, yourdata) as a first diagnostic check when plm(yourformula,

issues in plm using random effect model
Dear Kailas Gokhale, The negative individual variance is not a problem with your code or plm. It a property of your data.

plm(..., model="within", effect="twoways") is very slow on unablanaced data (was: Re: Regressions with fixed-effect in R)
Hello Giovanni I made a minor modification to your function, which now allows to compute the within R-sq in Twoways Within models (see below). However I ran into an issue that I have already encountered before: whenever I try to fit Twoways Within models on my unbalanced data, the process is strangely slow and I usually terminate it either after ~15min or when my CPU hits 100C. This is similar to

Unexpected result with lag() et diff() in plm package.
I have an unexpected result with the functions lag() and diff() in the plm (panel data) package when used with transform(). These plm-specific functions are supposed to generate lags and first differences within each panel. lag() does not work properly the first time (it reproduces the same series--this is a common time series pitfall), BUT then it does work properly when it is run a second

R: plm and pgmm
dear giovanni--- thanks for answering on r-help to me as well as privately. I very much appreciate your responding. I read the plm vignette. I don't have the book, so I can't consult it. :-(. I am going to post this message now (rather than just email it privately), because other amateurs may have similar questions in the future, and find this message and your answers via google.

Using relaimpo or relimp with PLM and GLS
Dears, Unfortunatelly, the packages relaimpo and relimp do not seem to work with plm function (plm package) or gls function (in nlm package). I've been studying on how to adapt one of them for this pourpose. In that sense, I have two questions regarding to this work: 1) have anyone hard of any workaround for those incompatibilities, or at least of any ideas on that - especially for plm? 2)

Problem in plm package
Hello everyone, I am working with plm package and I have problem with random and within models, which are giving errors which says "empty model". However, the model is not empty. In the source code for plm.fit, where the error originates it says something like (writing from the top of my head...) X <- model.matrix(formula,data, lhs=1,...) if (ncol(X) == 0) stop("empty
