Witryna24 kwi 2024 · The bw.SJ function in the stats package and width.SJ in MASS package use Sheather Jones method. This is a very popular method, and hence I'll guess a lot of (if not all) packages for KDE will have an option to use this. For example, check out the dpik function from KernSmooth package. You can also explore the ks package. WitrynaImproved Sheather-Jones Algorithm # A different take on KDEs is the improved Sheather-Jones (ISJ) algorithm. It is an adaptive kernel density estimator based on linear diffusion processes, where the optimality is treated as solving the heat equation.
