WebAug 11, 2024 · Introduction. An outlier is a value or an observation that is distant from other observations, that is to say, a data point that differs significantly from other data points. Enderlein goes even further as the author considers outliers as values that deviate so much from other observations one might suppose a different underlying sampling mechanism. WebApr 11, 2024 · The research of TS additive OD algorithm based on residual statistics has been studied by many scholars at home and abroad. Yulistiani S. proposed an improved Bayesian information criterion for model selection and detection of potential outliers. The improved Bayesian information criterion for OD will be applied to outstanding loan data.

WebScatter plots often have a pattern. We call a data point an outlier if it doesn't fit the pattern. Consider the scatter plot above, which shows data for students on a backpacking trip. (Each point represents a student.) Notice how two of the points don't fit the pattern very well. These points have been labeled Brad and Sharon, which are the ...
