Figure 1
The two graphs are arranged horizontally. A legend at the bottom of both graphs identifies a solid line for “Quantile estimate”, a shaded region for “95 percent C I (Quantile)”, and a dashed line for “O L S estimate”. The horizontal axis in both graphs is labeled “Quantile” and ranges from 0.05 to 0.95 in increments of 0.10 units. Left Graph: The line graph is titled “Variation in the P I A coefficient over conditional quantiles”. The vertical axis is labeled “Coefficient of P I A” and ranges from 0 to 3 in increments of 1 unit. A horizontal dotted line passes through 0, running parallel to the horizontal axis. The data from the graph is as follows: The “Quantile estimate” line starts at (0.05, 0.08) and moves steadily upward, crossing the horizontal dashed line at the value of the 0.62 quantile, then rising sharply to end at (0.95, 2.10). The “95 percent C I (Quantile)” region surrounds the “Quantile estimate” line at (0.048, 0.021), (0.85, 1.781), (0.95, 3), (0.95, 0.996), (0.897, 0.064), and (0.048, 0.138). The “O L S estimate” line starts at (0.05, 0.73) and runs parallel to the horizontal axis to end at (0.95, 0.73). Right Graph: The line graph is titled “Variation in the P G W coefficient over conditional quantiles”. The vertical axis is labeled “Coefficient of P G W” and ranges from negative 2 to 2 in increments of 1 unit. A horizontal dotted line passes through 0, running parallel to the horizontal axis. The data from the graph is as follows: The “Quantile estimate” line starts at (0.05, 0.12) and moves in a relatively flat, fluctuating horizontal direction, remaining near the horizontal dashed line until the value of the 0.75 quantile, where it rises to a peak at (0.85, 0.75) before dropping to end at (0.95, 0.22). The “95 percent C I (Quantile)” region surrounds the “Quantile estimate” line at (0.05, 0.29), (0.749, 0.528), (0.847, 1.435), (0.95, 1.836), (0.95, negative 1.42), (0.847, 0.037), (0.744, negative 0.201), and (0.05, negative 0.007). The “O L S estimate” line starts at (0.05, 0.22) and runs parallel to the horizontal axis to end at (0.95, 0.22). Note: All numerical data values are approximated.Variation in the “PIA and PGW” coefficient over the conditional quantiles. Notes: Horizontal lines represent OLS estimates with a 95% confidence level. Graphs have been made using the “grqreg” Stata module. Source: Own elaboration
