Figure 12
The diagram shows a square plotting area. The horizontal axis ranges from negative 1.5 to 1.5 in increments of 0.5 units. The vertical axis ranges from negative 1.5 to 1.5 in increments of 0.5 units. A faint circle centered at the origin with radius 1.0 is drawn inside the plotting area. Gridlines extend vertically and horizontally through the origin. Eight blue points appear within the circle. The coordinates of the points are as follows: (negative 0.67, 0.15), (negative 0.66, negative 0.14), (negative 0.21, 0.56), (0.21, negative 0.54), (0.27, 0), (0.01, negative 0.7), and (0.96, 0.01). Note: All numerical data values are approximated.Unit circle diagram for model stability. Source: Authors
