Panel (a): Platform Certification Level S H A P Dependence. The horizontal axis is labeled “Platform Certification Level” and ranges from 0 to 5 in increments of 1. The vertical axis is labeled “S H A P value” and ranges from negative 0.50 to 0.50 in increments of 0.25. Points appear in vertical clusters at discrete certification levels. Lower levels around 0 to 2 are mostly negative, centered near approximately negative 0.15. Higher levels around 3 to 4 are strongly positive, reaching approximately 0.45. Point color represents Total Number of Reviews, which ranges from negative 1 to 2 in increments of 1 unit. Panel (b): Lake View S H A P Dependence. The horizontal axis is labeled “Lake View” with binary values 0 and 1. The vertical axis is labeled “S H A P value” and ranges approximately from negative 0.1 to 0.1 in increments of 0.1. Two vertical clusters are shown. Lake View equals 0 is centered slightly below zero, while Lake View equals 1 is centered clearly above zero, with values reaching approximately 0.12. Point color represents Area which ranges from negative 1 to 2 in increments of 1 unit. Panel (c): Facility Index S H A P Dependence. The horizontal axis is labeled “Facility Index” and ranges from approximately 2.5 to 10 in increments of 2.5. The vertical axis is labeled “S H A P value” and ranges from negative 0.50 to 0.50 in increments of 0.25. A scatter distribution with a smooth curve is shown. The trend curve rises from approximately negative 0.20 at low index values, crosses above zero near approximately 3, peaks near approximately 0.26 around 7, and then declines slightly toward approximately 0.10 near 10. Data points are scattered around the trend curve. Point color represents Service Index, which ranges from 2.5 to 7.5 in increments of 2.5 units. Panel (d): Area- Facility Index S H A P 2 D Dependence. The horizontal axis is labeled “Area” and ranges from approximately negative 1 to 2 in increments of 1. The vertical axis is labeled “Facility Index” and ranges from 0 to 10 in increments of 2.5. Points are colored by S H A P value. Lower area and lower facility index regions show darker colors, indicating lower S H A P values. Higher area and higher facility index regions show warmer colors, indicating higher S H A P values, with the strongest values concentrated in the upper right region. Data point color represents S H A P values, which ranges from negative 0.4 to 1.22 in increments of 0.4 units. Note: All numerical values are approximated.Combined SHAP dependence plots.
