ash2 {ash} | R Documentation |
Compute bivariate ASH estimate (product polynomial kernel)
ash2(bins, m, kopt)
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. |
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.
# Continuing example from help(bin2) m <- c(5,5) f <- ash2(bins,m) image(f$x,f$y,f$z) contour(f$x,f$y,f$z,add=T)
