Difference between LOESS and LOWESS - Cross Validated Because of this small difference, lowess and loess will almost always give slightly different numerical results for large data sets lowess is in principle more accurate but the difference is generally small Where the difference between lowess and loess becomes significant is in terms of speed and memory usage
With a binary Y, why are Rs lowess fits so often flat? $\begingroup$ (+1) Helpful answer, and for your data I'm getting things to work fine, but after extensive trials I'm still finding these various commands to work inconsistently loess, lowess, and scatter smooth may or may not work on any given trial Different levels of "f" or "span" may fail to yield different degrees of smoothing (or else
scatterplot smoothing in r with big dataset: different methods The rest of the code plots the subsampled raw data, the subsampled smooth (in gray), a lowess smooth of the subsampled smooth (in red), and a lowess smooth of the subsampled data (in blue) The last, although very easy to compute, will be much more variable than the recommended approach because it is based on a tiny fraction of the data
Practical description of LOESS and smoothing splines? Again, as described by in Cleveland[1], LOWESS downweights observations with large residuals rather than specifically select and remove them However, some observations may get zero weight, which means some are effectively removed Specifically, after an initial fit LOWESS introduces robustness weights based on the residuals from the initial fit
How does lowess handle gaps in time series? - Cross Validated $\begingroup$ @Krautsultan I can't comment on the results you are seeing without knowing what they are, but the answer still applies: lowess would interpolate for the points that were not seen in the data If lowess does not work for your data, it may be the case that you simply need to use something else $\endgroup$ –
How do you get the regression equation from OLS and Lowess in R? $\begingroup$ @Frank Harrell explains the lowess case below (+1) For help on how to get the regression equation for the OLS straight line, see here (simplified answer), or here (more comprehensive) $\endgroup$ –
lowess: R ( python-statsmodels) vs MATLAB ( biopython) $\begingroup$ R actually has (at least) two lowess implementations (lowess and loess), both of which are controlled with several parameters Unless you consult the documentation for all your software and carefully make sure you are matching parameters correctly, any differences you are observing could be attributed to differences in default
