PURPOSE
This app can be used to create a Poincare plot with a confidence ellipse from a specified alpha value.
INSTALLATION
Download Poincaré plot.opx file, and then drag-and-drop onto the Origin workspace. An icon will appear in the Apps Gallery window.
NOTE: This tool requires OriginPro.
DESCRIPTION
A Poincare Plot, aka return map, is usually used to quantify self-similarity in process. Given a time series of the form {x1, x2, x3, ..., }, a poincare map will have a first point (xt, xt+1), then (xt+1, xt+2), then (xt+2, xt+3), and so on.
The stddev on both directions will be calculated and labeled. As well, the confidence ellipse will by given an alpha value.
