Dear R community, I have a project with electricity load forecasting, and I got hourly data for system load. If you haven't worked with electricity before, seasonality comes in many flavors: a daily pattern, with a peak at around 7pm; a weekly pattern, in which we use more electricity on weekdays in comparison to weekends; a winter-summer pattern, with air conditioning and heaters playing an important role, etc.
In SAS, I could specify an ARIMA with multiple seasonality terms, say (1,0,1) with period=24, and (1,0,1) with period=168 (I don't remember the orders I was using). This is how many studies I found on IEEE were modeling electricity load and it worked pretty well with the data I have. However, I can't seem to find how to do that in R. I've read the help files a few times, but to no avail. Is it possible? I hope I'm missing something straightforward. Thank you, Paulo Tanimoto University of Arizona ______________________________________________ [email protected] 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.
