The larger the value of the rank, the higher the impact of the event. * PHQ Rank is independent of the event’s location. * PHQ Rank for non-attended categories and unscheduled categories are further explained under each category. * PHQ Rank is comparable between attended events in terms of the event’s size or impact. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.predicthq.com/getting-started/predicthq-data/ranks/phq-rank.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
