similar to: Residuals for fracdiff

Hi I'm using fracdiff package to estimate the parameters of a fractionally-differenced ARIMA (p,d,q) model, and it works fine, but I wanted to have also the filtered series and the series of residuals. I understand these are calculated in the subroutine fdfilt, in the program fdcore.f, but I can't manage to get them out. Any suggestion would be much appreciated Thanks Susana Barbosa

Hi. I''m upgrading a project from an 0.8.0 pre-release gem to 0.8.2. I''ve installed the 0.8.2 gem, and the rspec_on_rails 0.8.2 plugin: ruby script/plugin install svn://rubyforge.org/var/svn/rspec/tags/REL_0_8_2/rspec When I try to run my specs though, I get the below error. It''s as if the spec_helper cannot find "spec/rails". I''ve noticed that

Hello everybody! I'm quite new using R and i'm trying to develope a function, but i have a problem. What i want to build is something like an objects vector. I have a list with two tables, and after or next to them, I want to add more tables or vectors to that list one by one. But i cannot find how to do it! Does someone can help me? I will be very grateful for any of your help!

Hi, I used function StructTS some time ago to fit a structural model to a time series. Now with R 1.6.2-1 I repeated the analysis with the same series and I get the following error: Error in KalmanLike2(y, Z, -1) : invalid argument type I tried with other series and I get the same error; I checked the examples in the documentation and they work fine. I suspect I am missing something

Dear Sirs, I would like to kindly ask for your assistance on the folllowing issue. After uploading the most updated the versions of some libraries (namely: survival and nlme) I became unable to open R. Every time I try to open R a dialogue box pops up with the following message: --------------------------- Information --------------------------- Fatal error: unable to restore saved data in

Hi all I am one recent user of R and have a few doubts I did a binomial GLM with 3 - factor and now I have to test contrasts to identify that treatments are different. I know that the contrasts are used in ANOVA, it is not incorrect to use them in GLM? there is a way to do contrasts between treatments for GLM as a Tukey for the ANOVA? Susana

Not for all users but for some. I'm using samba 3.0.20 running on Fedora Core 3. Security = ADS, winbind works and getent passwd returns local unix accounts plus the domain accounts as expected. It also returns a lot of entries like: 6811ff15281f4d19bdc:x:18004:10000:Anel Susana Esquivel:/export/private/6811ff15281f4d19bdc:"/sbin/nologin" I suspect these are accounts in a

Hola Javier, Intenta los siguientes cambios g4 <- function(codigo_llega, n_caracteres){ codigo_llega <- as.character(codigo_llega) if(n_caracteres == 6) res <- substr(codigo_llega, start=0, stop=4) else res <- codigo_llega res } g4 <- Vectorize(g4) x <- c('Jorge Velez','Javier Marcuzzi','Daniel Merino','Susana deus Alvarez', 'Carlos

Antes que nada puedes encontrar documentación sobre la librería ggplot2 que es la que yo uso para gráficos como el que quieres hacer, aunque hay otros paquetes que te pueden ser útiles: http://docs.ggplot2.org/current/ Adicionalmente a lo dicho por Carlos aquí te van otros ejemplos (los agrego porque no nos proporcionaste datos con lo que pudiéramos ver mejor lo que buscas):

Dear all, I want to assess the question whether several time series of parties' respective popularities are fractionally integrated. The "fracdiff" package seems to be an obvious choice. What confuses me is that the 'd' parameter estimated by fracfiff seems to be bound to a range from 0 to 0.5. From what I have read I would assume it should be allowed to vary between 0 and

Hi, I'm using the function fracdiff and can not figure out how to get the estimated values for sigma2 or confidence intervals for the parameter estimates. Does anyone know how to obtain these values? Thanks, Melissa

I was sniffing in the fracdiff library (this is for fractionally integrated ARMA processes; Haslett and Raftery 1989). The documentation suggests that one tries the following simple example: library(fracdiff) ts.test <- fracdiff.sim( 5000, ar = .2, ma = -.4, d = .3) fracdiff( ts.test$series, nar = length(ts.test$ar), nma = length(ts.test$ma)) When I run this, I get the following error: R

Does anybody know if it is possible to forcast or predict from a fracdiff object? Any help would be much obliged... Cheers, Alan

Hi,I have a question about the fracdiff.var function (package fracdiff) which goal is to recompute more precise confidence intervals for the parameters estimated by fracdiff (or arfima). More precisely, it deals with the standard error of the "d" coefficient : Is it normal that the standard error of the "d" coefficient can be brought customly close to zero by decreasing the

Dear all, my problem is following. I know Stata, but currently I have to use R. Could You please help in finding the analogy to R. (1) creating of City-Dummy. I know in Stata: g byte city=0 replace city=1 if city==12&year==2000 and (2) Create a Time-Dummy-Variable g byte T2000=0 replace T2000=1 if year==2000 (3) I need the City DUmmy for the following combination: I have the

Hola, escribo porque tengo una gran duda como gráficas tan fáciles en Excel son tan difíciles en R? No consigo hacer una gráfica en R de estas características. Osea como puedo dividir por sitios por tamaños. En una planilla enorme tengo la primera columna son las estaciones (pero solo quiero las tres ultimas) y después muchos parámetros, en las columnas 46, 53 y 60 los promedios ponderados. Y no

Hello, I am working in a longitudinal study, with a categorical variable as a dependent variable (alcohol consumption: no use, use, abuse and dependence) with repeated measures (baseline, 1 year, 2 years). Besides I have another variable with two groups: control and experimental. I would like to analyze the evolution in each group, I have though in lme, but I am not sure if I can do an lme with
