Based on my prior knowledge, I can analyze the relationship between the ROE (Erythrocyte sedimentation rate) feature and the presence of chronic heart failure.

The Erythrocyte sedimentation rate is a test that measures how quickly red blood cells settle in a test tube during one hour. Normal ESR values range from 0-22 mm/hour for men and 0-29 mm/hour for women. However, it is important to note that these ranges may be slightly different depending on the laboratory and the age of the patient.

To determine the relationship between ROE and chronic heart failure, we can compare the typical values of ROE for patients with and without chronic heart failure.

Based on this analysis, the dictionary can be created as follows:

```json
{
    "no": [5, 8, 12, 15, 18],
    "yes": [22, 30, 35, 40, 45]
}
```

Please note that the ROE values provided in the dictionary are just examples and are not based on actual data. The actual values may vary depending on the specific dataset and analysis.
