integer numbers.
After pressing
[Open] in Open window,

The smallest error,
which belongs to a segment, greater than zero is reported in error threshold box.
[Test] and [Style for output]
Selecting Scheffe test and Numbered style for output:
[Plot]
Time series and
Segments are plotted in
plot pane.
[Plot][Dominants]
Shows
dominant change points by vertical red lines.
[Plot][Stamp]
Stamps
segments. Blue belongs
to Stamped segments (2nd order)
[Plot][UnStamp]
Removes “Stamp”
[Plot][Stamped]
Plots the “Stamped”
segments
[Plot][Extract]
Copies
the shown segmentation as a new Time Series into clipboard in ASCII text code.

[Error threshold] box
Also, you can
neglect the segments with the error less than an error threshold,
say 10.
Here are the
results which are the same for error threshold =10 for this example!
[Load] and [Save]
You can save your
execution to investigate the segmentations later. Download the executed file ts1a.txt.seg
into a directory and press [Load] button then select it to see how it works.
[Open] Multiple file
When opening files,
select multiple data files:
Then press [Open].
After execution is completed see the directory including selected files:
Change points of
segments are reported in the files, which their names includes “-OUT” . Statistical report is given in “Summary.txt”.
Matlab Interface
Will
be available soon.
