Description
While running the apriori algo for a project, Leverage returned (some) values > 1; I'm not doing anything exotic with the library and am working from a rather standard sparse matrix. Shouldn't Leverage take values within [-1,1]?
Happy to provide more context if needed.

Research direction
Start by reproducing the reported leverage result through the apriori algorithm with a standard sparse matrix input. Confirm the expected value range and reduce the report to a minimal example; done means the behavior is explained and, if incorrect, supported by a regression test.
