Outlier analysis is a method used to find unusual or rare items in a set of data. In many cases, these outliers can provide important insights or highlight problems that need attention.
Importance in Decision-Making
In areas like healthcare, understanding outliers can help professionals make better decisions. For instance, if a certain condition is more common in a small group of patients but rare in the general population, this might indicate a need for specialized treatment or further investigation.
Techniques Used
To identify outliers, various techniques and tools can be applied. These may include comparing data points against averages, visualizing data in charts, or using specific algorithms designed to spot patterns thatstand out from the rest.
Impact on Models
In the context of machine learning, analyzing outliers can improve how models operate. It helps refine their accuracy by ensuring they focus on the most relevant information. This can ultimately lead to better outputs, making models more trustworthy and effective in real-world applications, such as medical diagnosis.
