WebIn 1964, Savitsky and Golay proposed a method equivalent to LOESS, which is commonly referred to as Savitzky–Golay filter . William S. Cleveland rediscovered the method in 1979 and gave it a distinct name. The method was further developed by Cleveland and Susan J. Devlin (1988). LOWESS is also known as locally weighted polynomial regression.

At frequencies above the cutoff, SG filters have poor noise suppression; this unnecessarily reduces the signal-to-noise ratio, especially when calculating derivatives of … marybeth daiz

"WebGolay deﬁned his “complementary series”, which we call sequences, in his 1961 paper ([2]) in three equivalent ways. A proof of equivalence will follow the deﬁnitions. For the ﬁrst deﬁnition, we need the notion of a separa-tion of a sequence. A separation of length jof sequence a= a 0 a 1 a n 1 " - Golay equation
