seasonal adjustment
Are any seasonal adjustment programs, like Tramo/Seats, Census X12 ARIMA or Berliner Verfahren implemented in R? I am doing a simulation study and I don't know how to adjust the series in R.
The possibility to access external the exe.files of the seasonal adjustment programs seems to be quite difficult.
Can anyone help me?
Thanks,
Ingo

Any tools for working with US 2000 census data?
I've been given the job of extracting some data from the United States
2000 census (files at
http://www2.census.gov/census_2000/datasets/Summary_File_2/Maryland/all_
Maryland.zip 52M). I'm only interested in Census Block Groups (CBGs)
located within Baltimore City, Maryland. Additionally, I just have to
extract certain data fields. I think I'll be using Summary File 2. This

seasonal fractional ARIMA models
Hello,
does anyone know about:
a) simulating seasonal ARIMA models? arima out of package ts can fit it,
but it does not look like it can simulates data from seasonal models
b) fitting and simulating fractional seasonal ARIMA models?
Hints will be appreciated,
Henning

[gently off topic] arima seasonal question
Hello R People:
When using the arima function with the seasonal option, are the seasonal
options only good for monthly and quarterly data, please?
Also, I believe that weekly and daily data are not appropriate for seasonal
parm estimation via arima.
Is that correct, please?
Thanks,
Sincerely,

How to write an estimated seasonal ARIMA model from R output?
I'm trying to use the following command.
arima (x, order = c(p,d,q), seasonal =list(order=c(P,D,Q), period=s)
How can I write an estimated seasonal ARIMA model from the outputs. To be specifically, which sign to use? I know R uses a different signs from S plus.
Is it correct that the model is:
(1-ar1*B-ar2*B^2-...)(1-sar1*B^s-sar2*B^2s-....)(1-B)^d(1-B^s)^D

problems whit seasonal ARIMA
Hello,
I have daily wind speed data and need to fit seasonal ARIMA model, problem
is that my period is 365. But when I use arima(...) function, with period
365, I?m getting error message: ?Error in makeARIMA(trarma[[1]],
trarma[[2]], Delta, kappa) : maximum supported lag is 350?. Can someone
help me with this problem?
Thank you

Question about fitting seasonal ARIMA in R?
Hi all,
I just couldn't find a R function which can fit multiple seasonal
patters... i.e. in the following code:
*arima(x = data, order = c(p, d, q), seasonal = list(order = c(P, D, Q),
period = S), ...
***
*
there can be only one "period", am I right?
What if the data seem to have three different seasonality cycles, 5, 12, 21?
Thanks a lot!

forecast: bias in sampling from seasonal Arima model?
Dear all,
I stumbled upon what appears to be a troublesome issue when sampling from an
ARIMA model (from Rob Hyndman's excellent 'forecast' package) that contains
a seasonal AR component.
Here's how to reproduce the issue. (I'm using R 2.9.2 with forecast 2.19;
see sessionInfo() below).
First some data:
> x <- c(
0.132475, 0.143119, 0.108104, 0.247291, 0.029510,

problem with seasonal arima
hallo to all
I've to calculate an arima model and I need only the
first and 365 th parameter and also the sar1 and the
intercept, so I'm traing with:
arima(X,order=c(365,0,0),seasonal=list(order=c(1,0,0),..),fixed=c(NA,rep(0,363),NA,NA,NA),transform.pars=F)
but the error answer is:
Error in polyroot(z) : polynomial degree too high (49
max)
also there are problems in allocating memory

Doing seasonal adjustment from within R
Is anyone aware of a way to seasonally adjust time series data using X-12 ARIMA and TRAMO/SEATS from within R? I know that that one can seasonally adjust data with gretl, which I understand offers some level of R integration. However, all the examples I've seen of gretl/R integration involve working interactively with gretl, while here I want to work interactively with R and call gretl in the

How can I calculate conditional mean in a large dataset including date data
Dear R users,
I have a dataframe with two columns: first column is date data (e.g.
1/1/2000 with character format: daily data from 1/1/1970 till 31/12/2003)
and second column is temperature value. Now I'd like to calculate mean for
each month in a year (i.e. May 2001, June 1997) and mean for each month in
all of years. As the number of days in some months is different from others

Can't add new users
Hi all,
I tried to add a new user to a Samba share, I did all the usual: made a Unix account on the Unix server for the user which was the same as the user's window's UID. Put her name as a valid user for that directory in server:/etc/opt/samba/smb.conf, and stopped and started server:/sbin/init.d/samba server; nothing worked.
Interesting observations: 1- After performing the steps

Seasonal ARIMA question - stat package (formerly ts)
To whom it may concern:
I am trying to better understand the functionality of 'R' when making
arima predictions to avoid any "Black Box" disadvantages.
I'm fitting a seasonal arima model using the following command (having
already loaded 'stat' package).
arimaSeason <-
arima(Data,order=c(1,0,1),seasonal=list(order=c(1,0,1),period=12))

now how can I put in the vector ?
bye for now,
Thanks a lot.
