similar to: ARIMAX

Hi R Users, I'm fairly new to R (about 3 months use thus far.) I wanting to use the arimax function from the TSA library to incorporate some exogenous inputs into the basic underllying arima model.Then with that newly model of type arimax, I would like to make a prediction. To avoid being bogged down with issues specific to my own work, I would like to refer to readers to the example

Dear ALL, I would appreciate if someone help me by letting me know the code of above model in R.I would request you to please let me know how i could make arimax model in auto.arima. Regards Ramanath [[alternative HTML version deleted]]

Hallo all can someone explain me how the exogenus variables work in the arimax models is not clear for me... Thanks Michele

Dear R-helpers, I would appreicate if someone can help me on the transfer parameter in ARIMAX and also see what I am doing is correct. I am using ARIMAX with 2 Exogeneous Variables and 10 years data are as follows: DepVar Period, depVar, IndepVar1 Period, indepVar1, IndepVar2 Period, indepVar2 Jan 1998,708,Jan 1998,495,Jan 1998,245.490 Feb 1998,670,Feb 1998,421.25,Feb 1998,288.170 Mar

Hi I'm trying to measure the effect of a policy intervention (Box and Tiao, 1975). This query has to do with the coding of the model rather than with the particulars of my dataset, so I'm not providing the actual dataset (or a simulated one) in this case, apart from some general description. The time series are of length n=34 (annual observations between 1977 and 2010). The policy

Dear List, The purpose of this e-mail is to ask about R time series procedures - as a biologist with only basic time series knowledge and about a year's experience in R. I have been using ARIMAX models with seasonal components on seasonal data. However I am now moving on to annual data (with only 34 time points) and understand that ARIMA is not suitable for these shorter time periods - does

Forescasting using predict() in an object of class arimax when there is an outlier IO in the model. Hi R users I have a problem when a use the predict() method in an object of class arimax ( These objects are the results of the implementation of the function arimax() from the TSA library) . The object is a model of a time series in which I identified an IO oulier at the element 33 of the serie

Dear list members, I am a (very) recent convert to R and I am hoping you can help me with a problem I'm having. I'm trying to fit a first-order transfer function to an ARIMA intervention analysis using the "arimax" function. The data was obtained from McCleary & Hay (1980) (via Rob Hyndman's Time Series Library: http://robjhyndman.com/tsdldata/data/schizo.dat). It has

Hi R team, We?ve run Arimax models in R. We had a lot of queries around the interpretation of the outputs. *Dependent variable =* Volume (Growth %) *Independent Variables =* 3 Macroeconomic variables (Growth %) Following is the line of code Arimax.Model <- auto.arima(y = input.data[,"Volume"], xreg = input.data[,model.vars], seasonal = F) Following is the output

Dear Lillian, I would request you if you provide me the knowledge of how build ARIMAX model in R? It would be great help for me. Thanks Ramanath [[alternative HTML version deleted]]

Hello, I try to simulate an ARMA-model using R, but I didn't find any function to generate such timeseries. In Splus there is the function arima.sim which generates AR-, MA- and ARIMA-series. Is there any similar in R? Best regards, Frank Beimfohr -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read

I'd like to play with ARIMA models of stock prices, but I am a complete novice. Could some kind soul explain the relationship among packages "ts", "tseries", "dse", "dse2", and "fracdiff"? Are they 'competing' products or does one depend on another? Where would be the best place for a novice to begin? Thanks for any advice. PS. I

(PLS, also CC: to 7ukwn@wanadoo.fr, which is my private address) Hi, I'm trying to setup 2 boxes with Asterisk; one with one quicknet PhoneCard, the other with two Quicknet cards: a PhoneCard and a LineJack; either boxes have a phone connected to the PhoneCards, a regular line is connected to the LineJack They'll be both on the internet (by adsl) and the purpose is to be able to make

I have just finished installing all the pieces of Redhat Linux 9 (2.4.20-8), Asterisk-0.9.1, Gnophone-0.2.4 on my IBM T30. Audio card is SoundMAX Integrated Digital Audio. Not sure what the chips are. But everything works on both W/XP and RH9. (Machine is obviously dual boot) Everything starts, Asterisk is up, sound/audio is great for CD player, Volume controls, Voice recorder, RealPlayer, etc.

Hi, I am trying to learn time series, and I am attending a colleague's course on Econometrics. However, he uses e-views, and I use R. I am trying to reproduce his examples in R, but I am having problems specifying a AR(1) model. Would anyone help me with my code? Thanks in advance!

Hola usuarios, Necesito detectar si existe o no un cambio de tendencia y si dicho cambio es significativo, para una serie temporal del tipo AirPassengers, en la que a partir de un determinado momento se ha hecho una campaña (supongamos que una promoción de vuelos). Para ello he pensado varios métodos: Usar la descomposición espectral de la muestra [decompose(AirPassengers)] y luego una Regresión

Hi, If I have data as follows: DATA_names<-c( "A mg kg" "B mg kg" "C mg kg" "D mg kg" "E mg kg" "F mg kg" "G mg kg" "H mg kg" How do I convert to: -1 A (mg kg ) -1 B (mg kg ) -1 C (mg kg ) -1 D (mg kg ) -1 E (mg kg ) -1 F (mg

I have an Internet PhoneCard for my IBM T30 running Linux RH9 2.4.20-31.9 and Asterisk 0.9.0. I have installed the appropriate Openh323 drivers. The card works and I can call to an extension that plays a recorded message, hang-up, call again and so forth. Suddenly, the subject error message starts appearing in the log, something goes into a loop, everything else in the system slows to a

Hello, I have a problem with creating an identity matrix for glmnet by using the contrasts function. I have a factor with 4 levels. When I create dummy variables I think there should be n-1 variables (in this case 3) - so that the contrasts would be against the baseline level. This is also what is written in the help file for 'contrasts'. The problem is that the function
