I have data with a tail to the right (gamma/lognormal/weibull dist.) I use the package abodOutlier to which returns angle-based outlier factor for each observation. A small abof respect the others would indicate presence of an outlier. This is the distribution of the abof:
The range of the abof is between 1.103859e-10 and 9.565497e-01 which is 0.0000000001103859 to 0.9565497... So my question is what interval should i consider as "outliers"? Is there anything standard for this method (say from 0 to 0.2 are outliers, or something along those lines) or should i just develop this interval specifically based on the company's interest and sensitivity?
