Generating model points

This notebook generates the sample model points used by the BasicTerm_S and BasicTerm_M models, by using random numbers. BasicTerm_S and BasicTerm_M are new business models, so no duration information is included.

Columns:

• point_id: Model point identifier

• age_at_entry: Issue age. The samples are distributed uniformly from 20 to 59.

• sex: “M” or “F” to indicate policy holder’s sex. Not used by default.

• policy_term: Policy term in years. The samples are evenly distriubted among 10, 15 and 20.

• policy_count: The number of policies. Not used by default.

• sum_assured: Sum assured. The samples are uniformly distributed from 10,000 to 1,000,000.

Number of model points:

• 10000
