## bivariate ASH

### Description

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.
`kopt` | see `ash1`

### 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.

### See Also

`bin2`

### Examples

    # 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=TRUE)
