I can see that the usage condition is still contradictory to both Wikipedia as well as the reference in Pyclusterend docs.
Both Wikipedia and the reference indicate that a value closer to 1 indicate presence of clusters.

Result & interpretation is correct but might need to be more elaborated.

Since the code use distance^1 which will yield the 1 - Hopkins stats.
While, the Wikipedia version based on the original paper of Hopkins stats which use distance^d (d = dimension)
