Based on prior knowledge, we can assume that the installment_commitment feature represents the percentage of disposable income that a person dedicates towards paying installments. 

To analyze the relationship between installment_commitment and the task of whether a person receives credit or not, we can look at typical values for each target class.

Typical installment_commitment values for target class 'yes' (person receives credit) may include:
- 5.0
- 10.0
- 15.0
- 20.0
- 25.0

Typical installment_commitment values for target class 'no' (person does not receive credit) may include:
- 30.0
- 35.0
- 40.0
- 45.0
- 50.0

Based on this analysis, we can create a dictionary with the requested format:

```json
{
    "yes": [5.0, 10.0, 15.0, 20.0, 25.0],
    "no": [30.0, 35.0, 40.0, 45.0, 50.0]
}
```
