jaccard distance2 followers
Can anybody explain the jaccard distance function in Datameer. The documentation https://www.datameer.com/documentation/display/DAS60/GROUP_JACCARD_DIST does not really explain. What are the sets, for which the distance is calculated? For groups with less than 8 elements the function doesn't return any value, why? The order in the source table has an effect on the returned value. I don't have an idea for that fits to jaccard index or distance. Any help appreciated.
