Re: [R] auto.arima function in R
There is no auto.arima function 'in R'. Do give credit/blame where it is due (probably package 'forecast'). Without the reproducible example the posting guide asked for, we can only guess wildly. I at least decline to do so. On 20/11/2014 10:52, Akhil dua wrote: Hello every one, I am using daily data of the flight departure.

I am sorry for violating the guidelines but the data that I am using is highly confidential so I can't disclose it.I posted sample data just for giving the flavour of the data.

This happens, but then you need to simulate some data that show the effect. It's not happening with the fit from example(auto.arima), so clearly not always. -pd -- Peter Dalgaard, Professor, Center for Statistics, Copenhagen Business School Solbjerg Plads 3, 2000 Frederiksberg, Denmark Phone: (+45)38153501 Email: pd@cbs.dk Priv: pda...@gmail.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.
