Reinsurance checks

[micheles]

The user can do tons of mistakes in the input files. We need to make sure that the engine gives clear error messages in such situations. Cases to consider:

Checks in the policy file:

• [x] policy present in the exposure but missing in the policy.csv file
• [x] policy column should have no duplicated values
• [ ] Sum of fractions for prop treaties should be between >=0 and <=1
• [x] The liability and deductible columns should be float >= 0
• [x] The nonprop treaties should be 0 or 1
• [ ] Any condition in the order of the treaties? Shall we write in the documentation how the information is processed?

Checks in the reinsurance file:

• [x] treaties present in the reinsurance.xml but missing in the policy.csv file
• [x] type values are within prop, wxlr or catxl
• [x] The deductible, limit and max_cession_event columns should be float >= 0

Checks in the configuration file:

• [ ] aggregate_by conditions:
  • [x] missing aggregate_by=policy
  • [ ] multiple aggregate_by (i.e. aggregate_by=policy; taxonomy ok)
  • [ ] multiple aggregate_by (i.e. aggregate_by=taxonomy; policy wrong)
  • [ ] multiple aggregate_by (i.e. aggregate_by=policy, taxonomy wrong)
• [x] missing total_losses
• [ ] multiple loss types in reinsurance_file must be an error

Others

• [ ] scenario_risk starting from rupture or from GMFs
