Outlier detection

"Outliers occur regularly enough in real-world measurement data to constitute a significant practical problem that is not adequately addressed by traditional smoothing filters designed to reduce the effects of high-frequency noise. To address this problem, this paper describes a simple data cleaning filter for outlier detection and removal which is based on a causal moving data window that is appropriate to real{time applications like closed loop control." - an interesting paper about online outlier detection
