Satterthwaite Approximation of the Distribution of SPE Scores: An R-Simulation-Based Improvement of the R-PCA-Based Outlier Detection Method

Outlier detection is a significant challenge in Internet of Things (IoT)-based systems, which encompass a multitude of sensor nodes deployed for diverse applications. Ensuring accurate data transmission from these nodes to base stations is crucial, as outliers (fault/event/intrusion) can adversely impact data processing accuracy and overall Quality of Service. The principal component analysis (PCA) has gained popularity for outlier detection in …
