...buntu 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) vad.dif1 <- diff(vad) emp.dif1 <- diff(emp) (2) I make a data set: d <- ts.union(emp.chng=emp.dif1,lag.emp.chng=lag(emp.dif1,-1),twolag.emp.chng=lag(emp.dif1,-2), vad.chng=vad.dif1,lag.vad.chng=lag(vad.dif1,-1),twolag.vad.chng=lag(vad.dif1,...

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): R> dynformula(emp~wage+capital,log=list(capital=FALSE,TRUE),lag=list(emp=2,c(2,3)),diff=list(FALSE,capital=TRUE)) I see: emp ~ wage + capital rather than the complete model that is given in the paper: log(emp) ~ lag(log(emp), 1) + lag(log(emp), 2) + lag(log(wage), 2) + lag(log(wage), 3) + diff(capital, 2) + diff...

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 reading "Panel Data Econometrics in R: The plm Package" by Croissant and Millo available at http://cran.r-project.org/web/packages/plm/vignettes/plm.pdf and "Ho...

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

Hola a todos! Soy nueva en R y necesito hacer unos gráficos para una investigación, he explorado un poco y estoy intentando usar ggplot2 ya que hace gráficos de muy buena calidad...tengo los datos de varios años para diferentes grupos de empresas y los pretendo graficar tanto en un solo grafico como en varios (facet_wrap) pero tengo problemas con el eje de las X, ya que necesito que aparezcan los años es decir, 2003, 2004 y así ....y no X2003, X2004 que es como están apareciendo. Este es mi código: library(reshape2) library(ggplot2)...

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: city<-c("A","A","A","B","B","C") var<-c("...

..., some weeks ago). 2) fitting the simple models Simplest possible model: AR(1) with individual effects x(i,t)= a*(x(i,t-1)) + bi + c This is what Ivo asked for in the first place. As the usual example is on data from the Arellano and Bond paper, available in package 'plm' as > data(EmplUK) I'll use log(emp) from this dataset as 'x', for ease of reproducibility. Same data are available in Stata by 'use "http://www.stata-press.com/data/r7/abdata.dta"'. The Stata dataset is identical but for the variable names and the fact that in Stata you have to gen...

I have this situation: class Employee < ActiveRecord::Base belongs_to :designation end class Designation < ActiveRecord::Base end I do the following at the irb console: Step 1: Find an employee >> emp = Employee.find 3 => #<Employee:0x35a7d34 @attributes={"designation_id"=>"3", &quot...

...) (variable 4) is 4271 != length of others (4278) I got the function to output the length of the dataset and weights, which were both 4271. When I remove "weights=w" from the code. StepAIC start's running, but then I get the following error: Problem in stepAIC(lm(new ~ -1 + SIC3 + emp, data =..: number of rows in use has changed: remove missing values? I checked the data for missing values and there are none. I can't understand why the code works fine on it's own, but not in a function. -------------------------------- #Mean imp and results regimp <- function(...

I'm attempting to select a model using stepAIC. I want to use a forward selection procedure. I have specified a "scope" option, but must not be understanding how this works. My results indicate that the procedure begins and ends with the "full" model (i.e., all 17 independent variables)...

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 e-mail. Yet, when I click on message before I connect to the contact center, it doesn't have any counts. Here is

Hi. Am brand new to R and to mailing lists - have never posted anywhere before, so hope I do this right. Am using R 2.9.1 with lattice graphics (just installed, fully up to date). Am doing trellis xyplot with y (emp=employment), x (yearmo=a time measure) and conditioning variable (indf - factor describing industry) -- i.e., (emp ~ yearmo | indf), where all three variables are in a dataframe. The conditioning variable is a factor with a long text description (e.g., "Offices of bank holding companies and of...

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
