To analyze the relationship between the feature ROE (Erythrocyte sedimentation rate) and the presence of chronic heart failure, we can consider the typical ranges of values for ROE associated with each target class ('no' for no chronic heart failure and 'yes' for chronic heart failure).

Based on prior knowledge, we can assume the following typical ranges of values for ROE:

- ROE values below 10 mm/h are typically associated with no chronic heart failure.
- ROE values above 20 mm/h are typically associated with chronic heart failure.

Now, let's generate the dictionary with the requested format:

```json
{
	"no": [5.0, 7.0, 9.0, 8.5, 6.2],
	"yes": [23.5, 21.8, 25.0, 22.3, 26.7]
}
```

Please note that the values provided are just examples and may not represent the actual ranges accurately. The actual ranges should be determined based on domain-specific knowledge or data analysis.
