WebIt will estimate the "equivalent number of parameters" implied by the fitted curve. On the other hand, 'loess' is much slower than 'lowess' and occasionally fails when 'lowess' succeeds, so both programs are kept in R. When there is only one predictor variable and no prior weights, 'lowess' and 'loess' are in principle exactly equivalent. Weblowess is defined by a complex algorithm, the Ratfor original of which (by W. S. Cleveland) can be found in the R sources as file src/appl/lowess.doc. Normally a local linear …
