Fast Exact Kernel Smoothing

Uses recursive expressions to compute exact univariate kernel smoothers in log-linear time based on the method described by Hofmeyr (2019). The main general purpose function is fk_sum() which computes exact (or binned approximations of) weighted sums of kernels, or their derivatives. Standard smoothing problems such as density estimation and regression can be addressed directly using this function, or using the purpose-built functions fk_density() and fk_regression. Projection pursuit algorithms based on minimum entropy (ICA, Hyvarinen and Oja 2000), minimum density cluster separation (MDH, Pavlidis et al. 2016) and regression-type losses (PPR, Friedman and Stuetzle 1981) are implemented in the functions fk_ICA(), fk_ppr() and fk_mdh() respectively.
