A smooth curve through a set of data points obtained with this statistical technique is called a loess curve, particularly when each smoothed value is given by a weighted quadratic least squares regression over the span of values of the y-axis scattergram criterion variable. See more Local regression or local polynomial regression, also known as moving regression, is a generalization of the moving average and polynomial regression. Its most common methods, initially developed for See more In 1964, Savitsky and Golay proposed a method equivalent to LOESS, which is commonly referred to as Savitzky–Golay filter See more LOESS makes less efficient use of data than other least squares methods. It requires fairly large, densely sampled data sets in order to … See more As discussed above, the biggest advantage LOESS has over many other methods is the process of fitting a model to the sample data does not begin with the specification of a function. Instead the analyst only has to provide a smoothing parameter value and … See more • Degrees of freedom (statistics)#In non-standard regression • Kernel regression • Moving least squares • Moving average • Multivariate adaptive regression splines See more
