Please, I need help to successfully run the Stanhel and Donoho Estimator on my data to flag outlyingness. I have a four column data with the summary presented below:
I did some study on Stanhel and Donoho estimator with some good help from here. I discover one of the problems I may have with my data is the presence of zeros. How do I handle this and correctly flag outlyingness using outlyingness function in r?
At the moment, I get this warning in r:
And the result returns NULL for outlyingnessX, outlyingnessZ, cuttoff, flagX, flagZ, singularSubsets and dimension.
If possible, please suggest an alternative or adjusted method to flag outlyingness.
