ash2 {ash}R Documentation

Compute bivariate ASH estimate (product polynomial kernel)

Usage

ash2(bins, m, kopt)

Arguments

bins (input list) bin count matrix nc and interval matrix ab from bin2
m (input integer vector of length 2) x and y direction smoothing parameters. Default is 5 by 5.

Value

Matrix of ASH estimates returned. Components x,y,z can be given to the contour function directly. Other input variables returned in list for record keeping.
