Based on prior knowledge, when it comes to the target variable "Does this client subscribe to a term deposit?", it can be inferred that having a housing loan might have an impact on the decision. 

From the given feature "housing, has housing loan?", we can analyze the relationship as follows:
- Clients who have a housing loan (categorical variable: "yes") may be less likely to subscribe to a term deposit.
- Clients who do not have a housing loan (categorical variable: "no") may be more likely to subscribe to a term deposit.

Therefore, the possible values of the feature "housing" for the target class "no" are ["no"], and the possible values of the feature "housing" for the target class "yes" are ["yes"].
