panel question (plm)
Hello,
I am working on a data set (already as a plm.data object) located

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 (

Updating qvalue and xtable
Good Morning Everyone,
I was going through my list of FTBFS packages today and I fixed all my R
packages but 2: qvalue and xtable.
qvalue requires ggplot2
xtable requires: lsmeans, spdep, splm, sphet, plm
I am not doing any R anymore these days and in fact spot has been the one
maintaining most of my R packages these days (thanks spot!!), so I am not really
interested in maintaining more R

dividing ts objects of different frequencies
Hello,
I have two time series objects, 1 is yearly (population) and the other is
quarterly (bankruptcy statistics). I would like to produce a quarterly time
series object that consists of bankruptcy/population. Is there a pre-built
function to intelligently divide these time series:
br.ts = ts(data=br.df[,-1], frequency = 4, start=c(2001,1), end=c(2008,2))
distPop.ts = ts(data=distPop.df[,-1],

Exporting summary plm results to latex
Dear all,
I am trying to export my fixed effect results to Latex. I am using the plm package with the summary function. However, it does not look like apsrtable, stargazer, or any other package can accompany using the plm package.
I am interested in a classic table with the coefficient in one row followed by the standard error in paranthesis in the next row and stars by the coefficient to show

plm Issues
Hi List
I'm having difficulty understanding how plm should work with dynamic
formulas. See the commands and output below on a standard data set. Notice
that the first summary(plm(...)) call returns the same result as the second
(it shouldn't if it actually uses the lagged variable requested). The third
call results in error (trying to use diff'ed variable in regression)

Panel models: Fixed effects & random coefficients in plm
Hello,
I am using {plm} to estimate panel models. I want to estimate a model that
includes fixed effects for time and individual, but has a random individual
effect for the coefficient on the independent variable.
That is, I would like to estimate the model:
Y_it = a_i + a_t + B_i * X_it + e_it
Where i denotes individuals, t denotes time, X is my independent variable,
and B (beta) is the

PLM package PGGLS strange behavior
When using the PLM package (version 1.2-8), I encounter the probem that
calling the FGLS estimator evokes strange behavior, when choosing the
"random" effects model. After calling the PGGLS function to estimate FGLS,
PLM gives me a warning, stating that the "random" model has been replaced
with the "pooling" model. I would, however, really like to estimate the

Longitudinal Weights in PLM package
Hi all,
I a semi-beginner with R and I am working with the plm package to examine a
longitudinal dataset. Each individual in this dataset has a longitudinal
weight for the probability that he or she remains in the sample.
Unfortunately, I have not found an argument to use weights in the plm
function? I tried ?weights=? like in standard lm or in nlme or lm4 but it
does not work. I asked the

Problems using log() in a plm() regression.
hey guys
I have a panel data set that i want to perform some regressions on. I am
using the /plm/ package.
I defined a model in the following way:
PWBw.pool <- plm(*PWB* ~ log(*I_EQON*) + log(*RD*) + ... + *PAGRI*,
data = pfem, na.action=na.exclude, model="pooling")
When i run this it gives the following error (the error remains when i use

problem with "dynformula" from "plm" package
Hello list,
I'm following the paper (http://www.jstatsoft.org/v27/i02/paper) on how to
use "plm" to run panel regressions, and am having trouble with what I
believe should be something very basic.
When I run the command (p.9 in the paper):

using function instead of formula in plm
Hi all,
I am trying to use plm to estimate coefficients in a model consisting of a system of equations. So far I used mle2 from the package "bbmle", but now I need to test for autocorrelation and mle2 does not provide for the necessary tests. mle2 needs a function as input that might as well consist of many different equations. plm however requires an object of class formula that needs
