`corr = data.corr()` 是计算DataFrame `data` 中所有特征两两之间的相关系数矩阵。如果你想仅针对特定列(如'MEDV')计算与其他列的相关性,你可以这样做:
```python
# 先假设data是已经加载好的DataFrame
# 从x.data中创建DataFrame,如果x是pandas DataFrame或者sklearn的DataSet
data = pd.DataFrame(x.data, columns = x.feature_names)
# 计算CRIM与MEDV之间的Pearson相关系数
crim_medv_pearson_corr = data['CRIM'].corr(data['MEDV'], method='pearson')
# 对于Spearman秩相关系数
crim_medv_spearman_corr = data['CRIM'].corr(data['MEDV'], method='spearman')
# 对于Kendall等级相关系数
crim_medv_kendall_corr = data['CRIM'].corr(data['MEDV'], method='kendall')
print("Pearson correlation: ", crim_medv_pearson_corr)
print("Spearman rank correlation: ", crim_medv_spearman_corr)
print("Kendall rank correlation: ", crim_medv_kendall_corr)
```
这会返回CRIM和MEDV之间对应的三种相关系数。
