LOF return Nan values
isamsing opened this issue · comments
I have been using LOF for analysing more than 10,000 data point. However, the lof function in dbscan package return nan value.
Can you share a (small) dataset that produces NAN values with me?
Hello Micheal,
Thank for looking into the issue. I have attached the .csv file with this email.

I seem to not be able to see your attachment. Can you email it directly to me at michael at hahsler.net?
The problem was that the data has more than k duplicate points. The new version returns now 1 instead of NaN. However, the LOF paper suggests to first remove duplicates before running LOF.
