Abstract

Outliers are the data that do not follow the normal/hypothesized trend of data. They are an ‘atypical’ or even a ‘rare’ or ‘anomalies’ or ‘abnormal’ data points that do not follow the flow. Detection of outliers is the primary step in obtaining results of any statistical or machine learning analysis. It is important to note that there is no fixed equation or methodology for finding outliers. We, of course, have a definition, but, what may be an outlier to one person may not be an outlier to someone else. In this paper, we will present a few outlier techniques employed on colon cancer data. We will proceed to identify which among the few testing techniques are more fruitful in identifying outliers in our dataset.
