tiny.xls with one spreadsheet (daily data)
Column B is the target series of the forecast because there rows 16-22 are empty. Note that with that few data points no useful forecast can be done. This example merely exists to demonstrate the input format for this website's forecast algorithm.
Hourly data
Extract from hourly.csv with rows hidden.
Column B is the target series because there all cells after row 9138 (Jan 16, 2013) are empty while all other series are complete until Feb 16, 2013.
15-minute data
Auszug aus 15mins.xls
Column F is the target series because there rows 2-1441 are empty.
The data is generated following a simple principle: F(t)=B(t-1)+C(t-2)+D(t-3)-E(t-4) as also depicted with colors in the image.
Note that the order of the data (i.e., of each point in time) is reversed. The system deals with data both in increasing and decreasing order of time.
