The data that arrives is almost always recorded as a new entry. The data typically arrives in time order. Time is a primary axis (time-intervals can be either regular or irregular).
A time series is a series of data points indexed (or listed or graphed) in time order. Most commonly, a time series is a sequence taken at successive equally spaced points in time. Thus it is a sequence of discrete-time data. Time series database - Time series - Decomposition of time series.
Time Series Data Library. The Time Series Data Library (TSDL) was created by Rob Hyndman, Professor of Statistics at Monash University, Australia.
Time series analysis accounts for the fact that data points taken over time may have an internal structure (such as autocorrelation, trend or seasonal variation) that should be accounted for. 27 May - 5 min - Uploaded by Wild About Statistics Index: ~wild/wildaboutstatistics/) We'll learn to plot series of.
