[Proposal] Hazard Analysis type codelist

[odscrachel]

What is your proposed change?

To create a new codelist for field event_set.analysis_type. This will also be used by loss.hazard_analysis_type. Spreadsheet link

Title	Field name	Description	Type	Codelist
Analysis type	event_set.analysis_type	The type of analysis used by the hazard model: probabilistic (multiple potential events characterised by different intensity and occurrence frequency); deterministic (frequency-independent representation, such as mean, median or max); empirical (obtained from real event observations).	string	probabilistic, deterministic, empirical

Looks good, but we should avoid documenting the codes and their meanings in the field's description. That information should go in the codelist CSV file in order to maintain a single source of truth and avoid things getting out of sync if updates are made in the future.

In that case I propose we have:

Title	Field name	Description	Type	Codelist
Analysis type	event_set.analysis_type	The type of analysis used by the hazard model.	string	probabilistic, deterministic, empirical

We can then add the information about each code in the codelist CSV/ documentation

Code,Label,Definition
probabilistic,Probabilistic,Probabilistic risk assessment simulates a large number of synthetic events to estimate their likelihood and severity and estimate overall risk.
deterministic,Deterministic,"Deterministic approaches analyse disaster scenarios (e.g., historical or worst-case events) to estimate their impact, but do not consider the full range of possible outcomes and do not quantify the likelihood of each impact."
empirical,Empirical,"Analysis or data relying on observations, such as hazard intensity recorded during a post-event surveys."
