You asked the same question about these results 3 days ago. The results are not significantly different. You were told that the very small differences can be caused by lots of factors and you are not providing relevant information about e.g. OS, 32bit/64bit. Besides you are using an old version of R. I really don't think there is anything to worry about. /Berend -- View this message in context: http://r.789695.n4.nabble.com/Difference-in-function-arima-estimation-between-2-11-1-and-R-2-12-2-tp3807782p3808170.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
