Hi, I would like to regress y (dependent variable) on x (independent variable) and y(-1). I have create the y(-1) variable in this way: ly<-lag(y, -1) Now if I do the following regression lm (y ~ x + ly) the results I obtain are not correct. Can someone tell me the code to use in R in order to perform a regression using as explanatory variable a lagged dependent variable? My best regards,

Hi, I would like to count the columns of a data.frame. I know how to count the rows, but not the columns. Can someone tell me how to do it? My best regards, Giacomo Moro --------------------------------- [[alternative HTML version deleted]]

x<-c(-1.873....,-0.121) # 23 numerics; x.arma12 <- armaFit(x ~ arma(1,2)) #estimates y[t]= -0.11465 - 0.23767 y[t-1] - 0.14230 e[t-1] -0.85770 e[t-2] + e[t]; # ? how to predict 46 steps ahead based on 23 data points? # the following doesn't work since n is in armaSim rather than armaFit; predict(x.arima12, n.ahead=46) # Thanks ---------------------------------

Wow, commenting those two lines worked out fine for me, thanks!

Thanks, Also, every method inherited by LoopBase causes the same error, while Loop methods go smooth.

I think I am in the first case, but I don't understand something, the -load option during which command? opt? and which file should I load? libz3.so?

Sorry for the silly question. I am trying to perform a simple operation on a subsample of my data loaded as data and attached: data<-read.dta(name file) attach(data) Say x=1,2 and y=4,5 I want to summarize z only if x=1 & y=4. I thought that the way to do that would be to write if((x=1) & (y=4)) summary(z) butwhen I do this the result I get is for the whole data (irrespective of

Dear R users, I have to call fortran program from within R (R 2.8.1 on ubuntu 8.10 machine). Suppose I have a fortran code like this (this is only a toy model, my working model is far more complex, but input/output is similar) DOUBLE PRECISION FUNCTION model(times, alfa, beta) DOUBLE PRECISION alfa, beta, times model=beta*sin(times)+alfa*cos(times) END FUNCTION which

Hello, I've just installed dovecot to replace courier-imap and I've found out it didn't support some of the typical LDAP userPassword schemes, so I've written some based on OpenSSL API. Furthermore I noticed that the MD5 one seems broken. If it isn't a requirement to ship its own implementation of a crypto algorithm, I would send in a patch to replace schema checks with
