Software solutions for identifying outliers [PDF]

open access: yesComputational Methods in Social Sciences, 2015
An outlier is an observation that appears to deviate evidently from other observations in the sample. It is important to identify an outlier because it may suggest erroneous data or, in some cases, outliers may be due to random variation or may indicate ...

On Selection Criteria for the Tuning Parameter in Robust Divergence

open access: yesEntropy, 2021
Although robust divergence, such as density power divergence and γ-divergence, is helpful for robust statistical inference in the presence of outliers, the tuning parameter that controls the degree of robustness is chosen in a rule-of-thumb, which may ...
