In data analysis, identifying outliers or anomalies is crucial for understanding the data and ensuring its accuracy. In this post, we'll explore outlier detection techniques using Python and its data analysis libraries, namely NumPy and scipy. We'll cover the Z-score method, IQR method, and DBSCAN algorithm to detect anomalous data points. Understanding outliers: An outlier is a data point that deviates significantly from other data points in the dataset. This could be due to measurement errors, recording errors, or they might represent rare events. Outlier detection techniques help us identify these data points and validate or reject them, leading to more accurate results. Using NumPy: We'll begin by exploring outlier detection using the Z-score method with NumPy. This method measures the number of standard deviations a data point is away from the dataset's mean. This'll help us identify data points with extreme values. Moving on to scipy's IQR method: The Interquartile Range (IQR) method is another common technique that determines outliers based on the boxplot. A point lying outside the whiskers on a boxplot is considered an outlier. Lastly, we'll delve into DBSCAN algorithm: DBSCAN is a density-based clustering algorithm that can identify outliers as well. By defining a threshold, DBSCAN groups points that have a minimal number of neighbors within an area, and any point without that minimum number becomes an outlier. Don't miss out!
