Figure A1
The horizontal axis labeled “H I underscore c” and ranges from negative 2 to 2 in increments of 1 unit. The vertical axis ranges from 0 to 100 in increments of 20 units. The plot shows a line and several data points. A legend identifies the two entries: a solid line as “Fitted values” and plotted points as “H H D”. The “H H D” data points begin near an “H I underscore c” value of approximately negative 2, with an “H H D” value near 15. The points are scattered across the graph with moderate vertical spread. As “H I underscore c” increases, the points generally shift upward. The highest points appear near an “H I underscore c” value of approximately 0.4, with an “H H D” value near 90. The fitted values line begins near approximately 15 at an “H I underscore c” value of negative 2, increases gradually across the axis, and ends near approximately 33 at an “H I underscore c” value of 1.7, indicating a slight positive linear trend across the observed range. Note: All numerical data values are approximated.Fitted values for happiness and household debt. Source: Authors’ own work
