http://rafalab.dfci.harvard.edu/dsbook/smoothing.html Smoothing may be used in two important ways that can aid in data analysis (1) by being able to extract more information from the data as long as the assumption of smoothing is reasonable and (2) by being able to provide analyses that are both flexible and robust. See more In statistics and image processing, to smooth a data set is to create an approximating function that attempts to capture important patterns in the data, while leaving out noise or other fine-scale structures/rapid … See more • Convolution • Curve fitting • Discretization • Edge preserving smoothing See more In the case that the smoothed values can be written as a linear transformation of the observed values, the smoothing operation is known as a linear smoother; the matrix representing the … See more One of the most common algorithms is the "moving average", often used to try to capture important trends in repeated statistical surveys.
