Title: Any quick way to smooth out plots?
Post by: Tragesty on April 25, 2012, 06:33:13 pm

My class is currently progressing through time series, and the smoothing of plots, including moving mean and moving median and such seems very tedious by hand (5 number average, next 5 number average). Is doing it by hand the best way, or does anyone have any suggestions of doing moving median/mean in the CAS quicker (some formula or something)? Sorry if this seems like a silly question! Would be greatly appreciated.

Are you talking about seasonal data? If so, you'll soon be learning some formulae to help you out. :)
