A few species are grown as ornamental plants, the fine-textured ones used for clipped bordering. All grow best in free-draining sandy soil, unfertilized, and in full sun. "Artemisia stelleriana" is known as Dusty Miller,
Additive smoothing Additive smoothing In statistics, additive smoothing, also called Laplace smoothing (not to be confused with Laplacian smoothing as used in image processing), or Lidstone smoothing, is a technique used to smooth categorical data. Given an observation formula_1 from a multinomial distribution with formula_2 trials, a "smoothed" version of the data gives the estimator: where the "pseudocount" "α" > 0 is a smoothing parameter. "α" = 0 corresponds to no smoothing. (This parameter is explained in below.) Additive smoothing is a type of shrinkage estimator, as the resulting estimate will be between the empirical probability (relative frequency) formula_4, and the uniform
