time series
A brief overview of the main aspects of times series
This video above is a short summary of the centring process. The video below does a number of worked examples for time series smoothing (even and odd). Note, the tutor uses a different calculator so ignore her instructions. |
Detailed explanation of smoothing using median and mean - this outlines all the required steps for both even and odd smoothing. She also explains plotting straight onto the graph.
A clear example using TI-Nspire calculator for seasonalising and deseasonalising values. Definitely worth watching (remember we use ax+b)
