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     this help
