 Show Similar Jurisdiction Functionality

The "Show Similar Jurisdiction” functionality is based on a nearest neighbor data analysis - a distance matrix computer science algorithm which identifies the three most similar EHE counties/areas based on a given jurisdiction’s EHE indicator data points. The purpose of using a nearest neighbor analysis is to examine progress across all six indicators and find the data points (or other jurisdictions) that are quantitatively most similar to the selected jurisdiction. In a distance matrix, jurisdictions are considered nearest neighbors not based on physical proximity, but in terms of an EHE progress profile. This EHE progress profile scales and weighs the data in such a way that no single indicator becomes disproportionately important; similar jurisdictions may be different along some indicators but will not be significantly different along all of them.

These similar jurisdictions may be interested in communicating with and exploring similar strategies as these similar jurisdictions in order to better achieve EHE goals.
