[R] Functions for autoregressive Regressionmodels (Mix between times series and Regression Models) ?
Hello everybody, I've a question about "autoregressive Regressionmodels". Let Y[1],.,Y[n], be a time series. Given the model: Y[t] = phi[1]*Y[t-1] + phi[2]*Y[t-1] + ... + phi[p]*Y[t-p] + x_t^T*beta + u_t, where x_t=(x[1t],x[2t],x[mt]) and beta=(beta[1],...,beta[m]) and u_t~(0,1) I want to estimate the coefficients phi and beta. Are in R any functions or packages for "autoregressive Regressionmodel" with special summaries?. I'm not meaning the function "ar". Example: I have the data working.time<- rnorm(100) # Y vacation<- rnorm(100) #x1 bank.holidays <- rnorm(100) #x2 illnes <- rnorm(100) #x3 education <- rnorm(100) #x3 Now I want to analyse: Y[t] = phi[1]*Y[t-1] + phi[2]*Y[t-1] + ... + phi[p]Y[t-p] + beta1*vacation_t +beta2*bank.holidays + beta3*illnes + beta4*eductation + u_t- Has anyone an idea? I would be more than glad if so. Thank you VERY much in advance.

[R] Problems using "lm" in combination with "predict"
Hello everybody, I'm trying to predict a linear regression model but it does not work. My Model: y = Worktime + Vacation + Illnes + Bankholidays My modelmatrix is of dimension 28x4 Then I want to make use of the function predict because there confidence.intervals are include. My idea was: mod <- lm(y~Worktime+Vacation+Illnes+Bankholidays) newdate=data.frame(x=c(324,123,0.9,0.1)) predict(y,newdate) But I always get the message: 'newdata' had 1 rows but variable(s) found have 28 rows What can I do?

[R] Text with differents colors in a plot / Detecting if text exists
Hi everybody,
I want to write some text in a plot.
That's simple I know. But I want to make use of different colors.
Eg. text(x,y,paste("Sunderland","high")).
Then Sunderland should be black and "high" red.
Has anyone an idea?
By the way. I'm looking for a function or something similar, that can check
whether there is text in some regions on the plot.
Because I don't want to overwrite an existing text with a new one.
Thank you so much for your help. I appologize in advance if my question is very
stupid but I have really no idea.
Yours,
Maja

[R] Problems with Vista, R 2.5.0 and function save
Hi everyone,
I want to make use of the save function but it did not work.
I'm using vista and R 2.5.0, winzip is installed too.
Here's the code (from example ?save):
> x <- runif(20)
> y <- list(a = 1, b = TRUE, c = "oops")
> save(x, y, file = "xy.Rdata")
Fehler in gzfile(file, "wb") : kann Verbindung nicht öffnen
Zusätzlich: Warning message:
kann komprimierte Datei 'xy.Rdata' nicht öffnen
Thank you so much for your help.
Background: I want to crate a variable "masterfile" that I can start with
data(masterfile) or attach(masterfile).
I.g.
Town<-c("London","Miami","Rio","Lansing")
Pollution<-c("34","32","50","17")
masterfile<-data.frame(Town,Pollution)
save(masterfile,file="masterfile.Rda")
Kindly regards,
Maja Schröter
