WebJul 5, 2024 · One approach to outlier detection is to set the lower limit to three standard deviations below the mean (μ - 3*σ), and the upper limit to three standard deviations above the mean (μ + 3*σ). Any data point that falls outside this range is detected as an outlier. As 99.7% of the data typically lies within three standard deviations, the number ... WebJan 13, 2024 · Clustering expectation-maximization method (Qin & et al., 2013; Yao & et al., 2024) enables to detect such outliers and anomalies that do not fit any model or belong to clusters that cover regular transactions. As used in Wang & et al (2024), outlier detection has become a common technique in data preprocessing so that the outlier …
