NAME

gbkreg2d - Kernel non linear regression for bivariate data

SYNOPSIS

gbkreg2d [options]

DESCRIPTION

2D kernel estimation of conditional moments. Data are read from standard input as triplet (x,y,z). The moments of z are computed on a regular grid in x and y The kernel bandwidth if not provided with the option -H is set automatically. Different bandwidths can be specified for x and y. Different moments are given in different data block. Options -n, -f, -H and -S accept comma separated values to specify different values for x and y components

OPTIONS

-n

number of points where the estimation is computed (default 10)

-f

fraction of the support for which to print the result (default .9)

-H

set the kernel bandwidth explicitly

-S

scale the kernel bandwidth with respect to heuristic 'optimal'

-K

choose the kernel: 0 Epanenchnikov, 1 Rectangular, 2 Silverman type I 3 Silverman type II (default 0)

-O

set the output, comma separated list of m mean, v standard deviation, s skewness and k kurtosis (default m)

-D

switch off data de-variation procedure

-v

verbose mode

-F

specify the input fields separators (default " \t")

-h
