Question

The feature of phone log data that is most predictive of wealth in Rwanda is:

1) Call duration
2) Number of calls made
3) Number of contacts in phonebook
4) Frequency of calls to family members

Answer 1

The feature of phone log data that is most predictive of wealth in Rwanda is the number of contacts in the phonebook.

Step-by-step explanation:

The feature of phone log data that is most predictive of wealth in Rwanda is the number of contacts in the phonebook. This is because having a larger number of contacts in the phonebook indicates a larger social network and potentially more connections and opportunities for wealth accumulation. For example, individuals with a larger number of contacts may have access to more job opportunities, business partnerships, and investment opportunities.

Other features such as call duration, number of calls made, and frequency of calls to family members may provide some insights into communication patterns and social relationships, but they are not as directly linked to wealth as the number of contacts in the phonebook.
