**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-His set automatically. Different bandwidths can be specified for x and y. Different moments are given in different data block. Options-n,-f,-Hand-Saccept comma separated values to specify different values for x and y components

**OPTIONS**

-nnumber of points where the estimation is computed (default 10)-ffraction of the support for which to print the result (default .9)-Hset the kernel bandwidth explicitly-Sscale the kernel bandwidth with respect to heuristic 'optimal'-Kchoose the kernel: 0 Epanenchnikov, 1 Rectangular, 2 Silverman type I 3 Silverman type II (default 0)-Oset the output, comma separated list of m mean, v standard deviation, s skewness and k kurtosis (default m)-Dswitch off data de-variation procedure-vverbose mode-Fspecify the input fields separators (default " \t")-hthis help
