gbkreg2d 6.2                                        June 2021                                        GBKREG2D(1)

       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

-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")
