Smoothing and Denoising
Remove unwanted spikes, trends, and outliers from a signal. Smooth signals using Savitzky-Golay filters, moving averages, moving medians, linear regression, or quadratic regression.

Discover important patterns in your data while leaving out noise, outliers, and other irrelevant information.
Take out irrelevant overall patterns that impede data analysis.
Filter out 60 Hz oscillations that often corrupt measurements.
Use median filtering to eliminate unwanted transients from data.
Resample and interpolate data measured at irregular intervals.
Detect and remove outliers using a simplified implementation of the Hampel algorithm.
