Figure 5
The horizontal axis of the histogram ranges from 0 to 50 in increments of 10, and the vertical axis ranges from 0 to 60 in increments of 10. Three dashed vertical lines are evenly spaced near 16, 32, and 48 on the horizontal axis, labeled “1st inauguration”, “2nd inauguration”, and “3rd inauguration”. The tallest bar is at 32, reaching 58, and another cluster of tall bars appears near 21, peaking near 49. Most higher bars are between 12 and 35. Bars farther left and right are shorter, under 10. Two dashed trend curves appear over the histogram. The main dashed bell curve rises smoothly, peaks near 21, and falls. A green dashed curve starts at 32, rises sharply to the peak, then declines concave-up. A blue dashed curve appears at the far right with a step-like pattern below the shortest bars. Note: All numerical values are approximated.Components of the proposed model and inauguration dates for the Portuguese case. Source: Figure by authors
