Hello, I am a beginner user of R and I would like to estimate a model with AR errors. I use arima function:
modele <-arima(conso,xreg=var.exogenes,order=c(ordre,0,0),include.mean=TRUE,method ="CSS") My inputs are dummies for each month except one, and the same thing for each day and each hour. I have this error message: Warning message: possible convergence problem: optim gave code= 1 in: arima(as.ts(conso), xreg = table, order = c(10, 0, 0), include.mean = TRUE, I try to estimate this model with SAS and I have a result. Have you a solution to solve this problem? Thank you very much, Gaelle Barrot ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
