Performing Time Series Analysis
Using the Time Series Platform
The Time Series platform lets you explore, analyze, and forecast univariate time series. A time series is a set y1, y2, ... ,yN of observations taken over a series of equally-spaced time periods. The analysis begins with a plot of the points in the time series. In addition, the platform displays graphs of the autocorrelations and partial autocorrelations of the series. These indicate how and to what degree each point in the series is correlated with earlier values in the series. You can interactively add:
a characterization of process disturbances
Spectral Density Plots
versus period and frequency, with white noise ...
