question about rolling regressions
Hi All,
I am using R 2.11.0 on a Ubuntu machine. I have a time series data set and
want to run rolling regressions with it. Any suggestions would be useful.
Here are the details:
(1) I convert relevant variables into time series objects and compute first
differences:
vad <- ts(data$ALLGVA/data$GDPDEF, start=1948, frequency=1)
emp <- ts(data$ALLEMP, start=1948, frequency=1)

problem with "dynformula" from "plm" package [RE-POST]
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):

dynformula(emp~wage+capital,log=list(capital=FALSE,TRUE),lag=list(emp=2,c(2,3)),diff=list(FALSE,capital=TRUE))
I see:

To convert an adjacency list model into a nested set model
Dear R-help
I am wondering if somebody wrote some code to convert an adjacency list
model into a nested set model.
In principal I want to do the same as John Celko mentioned it here with

trouble switching to 'plm' from 'xtabond' and Stata
Hello,
I am switching to R from Stata and I am having particular trouble with

geometric mean of probability density functions
Hi,
This is my first time posting to the mailing list, so if I'm doing something
wrong, just let me know. I've taken ~1000 samples from 8 biological
replicates, and I want to somehow combine the density functions of the
replicates. Currently, I can plot the density function for each biological
replicate, and I'd like to see how pool of replicates compares to a
simulation I conducted

Efficient way to determine if a data frame has missing observations
I have a data set covering a large number of cities with values for characteristics such as land area, population, and employment. The problem I have is that some cities lack observations for some of the characteristics and I'd like a quick way to determine which cities have missing data. For example:

pgmm (Blundell-Bond) sample needed)

Having no other regressors in the formula initially drove me crazy. This was a case where simpler models are

Problem running stepAIC within a function.
Hi
I need to a function that automatically fits a regression to data, using the
stepAIC. I've ran the code manually and it works fine. However, when I run
the function on the same data, the following error occurs:
Problem in regimp(fullsim = simt, fullsim1 = simt1,..: Length of (weights)
(variable 4) is 4271 != length of others (4278)
I got the function to output the length of the dataset

Forward stepwise procedure w/ stepAIC

Polycom 601 Message Center
While I know this is not a true asterisk problem, I figure someone where
may know. When you click on Messages and it gives you the count of
Urgent, New, etc. How can you make the phone gather that information?
For example, my phone shows me there is an e-mail. It also sends an

Using calibrate for raking (survey package)
I'm studying the calibration function in the survey package in preparation
for raking some survey data. Results from the rake function below agree
with other sources. When I run calibrate, I get a warning message and the M

between calibrated and raked weights is much more than I expected. I see

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
