Figure A2
The horizontal axis labeled “H I underscore c s q” and ranges from 0 to 4 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 are most densely clustered at low “H I underscore c s q” values between 0 and 0.5, where many observations are tightly packed and “H H D” values mainly fall between 5 and 38, with several higher points extending toward 80 and 90. A moderate level of scatter appears between “H I underscore c s q” values of approximately 0.5 to 1.5, where “H H D” values are more vertically spread and extend from near 0 up to around 45. The data become more widely scattered at higher “H I underscore c s q” values above approximately 2, where fewer observations are present and “H H D” values range broadly from near 0 to around 40. The sparsest region occurs near the upper end of the horizontal axis, close to “H I underscore c s q” equals 4, where only a small number of points are visible. The fitted values line begins at approximately (0, 28) and slopes slightly downward across the horizontal axis. Note: All numerical data values are approximated.Fitted values for the squared for happiness and household debt. Source: Authors’ own work
