PROGRAM:
NAME
gbker2d - Kernel density estimate for bivariate data
SYNOPSIS
gbker2d [options]
DESCRIPTION
2D kernel density estimation on an equispaced grid. Data are read from standard input as
couple (x,y). The kernel bandwidth if not provided with the option -H is set
automatically. Different bandwidths can be specified for x and y.
OPTIONS
-n number of points where the density is computed (default 10) use comma (,) to
specify different values for x and y components
-H set the kernel bandwidth explicitly; use comma (,) to specify different values for
x and y components
-S scale the kernel bandwidth with respect to euristic 'optimal' value; use comma (,)
to specify different values for x and y components
-K choose the kernel to use: 0: Epanenchnikov 1: Rectangular 2: Silverman type 1 3:
Silverman type 2 (default 0)
-D switch off data de-variation procedure
-v verbose mode
-F specify the input fields separators (default " \t")
-h this help
EXAMPLES
gbker2d -n 10,20 -K 1 < file
compute the kernel on an equispaced grid 10x20 using a rectangular kernel
