**Key insights:**
|
| 232 |
+
- **dist_subway** has a significant impact on pricing when at low values (green).
|
| 233 |
+
- **dist_store** demonstrates minimal impact on price.
|
| 234 |
+
- Higher age correlates with lower prices while lower age raises prices.

**Observations:**
|
| 243 |
+
- Prices spike for **distances lower than 900** based on the function f(x).
|
| 244 |
+
- Noteworthy **SHAP value at record[20] around 6500**.

**Contribution to Price:**
|
| 252 |
+
- **dist_subway** holds the largest positive contribution to price.
|
| 253 |
+
- **Age** follows as the second significant contributor.

+

|
| 258 |
+
|
| 259 |
+
**Insights:**
|
| 260 |
+
- Around **500 dist_subway**, there's a potential for both positive and negative impacts on price.
|
| 261 |
+
- Overall trend: closer proximity to the subway correlates with higher prices.
|
| 262 |
+
- An outlier at **6500 distance** from subway negatively impacts price, despite proximity to stores (dist_stores).

| 269 |
+

|
| 270 |
+
|
| 271 |
+
**Top Features for Errors:**
|
| 272 |
+
- **Age** stands out as the top feature impacting the top 5 errors negatively (for young ages).
|
| 273 |
+
|
| 274 |
+

|
| 275 |
+
**Top 1 Error:**
|
| 276 |
+
- Notably, young age has a negative impact on pricing (top 1 error).
|
| 277 |
+
|
| 278 |
+

|
| 279 |
+
**Insight from Errors:**
|
| 280 |
+
- Further distance from the subway might positively impact pricing for the top 5 errors.
|
| 281 |
+
|
| 282 |
+

|
| 283 |
+
**Error Instances:**
|
| 284 |
+
- Younger age negatively impacts price, while older age positively impacts it for the top 5 errors.
|
| 285 |
+
