Based on prior knowledge, the relationship between the feature "AGE" and the target variable (presence of chronic heart failure) can be analyzed.

The relationship between age and chronic heart failure is known to exist, with older individuals being more likely to have chronic heart failure. To analyze this relationship, we can examine the age distribution of patients with and without chronic heart failure.

Here is a dictionary representing the analysis:

```json
{
	"no": [45.0, 52.0, 55.0, 58.0, 62.0],
	"yes": [65.0, 68.0, 71.0, 75.0, 80.0]
}
```

The values provided in the lists for "no" and "yes" represent typical age values for patients without and with chronic heart failure, respectively.
