WebSep 15, 2024 · 3 Answers. Sorted by: 8. For this type of outlier a filter should work. For instance, a moving average is a filter, and can be applied here in a trend/noise decomposition framework: T i = 1 n ∑ k = 0 n − 1 x i − k N i = x i − T i. When the noise component is "too large" it indicates an outlier.
