Image 4: Plot of region-projection results

Postscript version of image

This plot shows the results of the rproj() call using the default values: 10 points were used along each axis and the range was calcualted automatically. The two contours are drawn at the 68.3% and 90% confidence levels.

From the PROJECTION runs on the individual parameters we expect the 90% confidence range to be 1.3-1.8 and 2.1-2.7; the automatically calculated range is larger than this which accounts for the poor quality of the contours. The plot needs to be re-evaluated using more points, and with a better choice of the axes.
