How to plot unit roots of companion matrix in OxMetrics
On page 7 of the Econometrics note a plot of the unit roots of the companion matrix is included. After I've formulated and estimated my model using the PcGive module, I click the PcGive Modul again and choose 'Test...'. I then choose 'Dynamic Analysis and Cointegration Tests...'
Then I choose 'Plot roots of companion matrix'
Then I have the plot. Followingly, I can right click on the graph and choose 'Edit Graph' and style it. One nice feature is, if you enter 'Graph layout' and set the 'Aspect ratio (Y scale)' to 'Square', you'll end up with a circle. Further, under 'Area 1', 'Y-axis', under 'Location and transformation' for 'Anchor' you may choose 'Use specified anchor' and set the X anchor to 0 in order to put your locate your Y-axis in the center of the circle. You may choose to do the same for your X-axis, if you like.
After editing, choose 'File' and 'Save as' and output your nice new plot.
