.SH NAME
gbker2d \- Kernel density estimate for bivariate data
.SH SYNOPSIS
.B gbker2d
[\fI\,options\/\fR]
.SH 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 \fB\-H\fR
is set automatically. Different bandwidths can be specified for x and y.
.SH OPTIONS
.TP
\fB\-n\fR
number of points where the density is computed (default 10) use comma (,)
to specify different values for x and y components
.TP
\fB\-H\fR
set the kernel bandwidth explicitly; use comma (,) to specify different
values for x and y components
.TP
\fB\-S\fR
scale the kernel bandwidth with respect to euristic 'optimal' value; use
comma (,) to specify different values for x and y components
.TP
\fB\-K\fR
choose the kernel to use: 0: Epanenchnikov 1: Rectangular 2: Silverman
type 1 3: Silverman type 2 (default 0)
.TP
\fB\-D\fR
switch off data de\-variation procedure
.TP
\fB\-v\fR
verbose mode
.TP
\fB\-F\fR
specify the input fields separators (default " \et")
.TP
\fB\-h\fR

.SH EXAMPLES
