NAME

       gbkreg - Kernel non linear regression function

SYNOPSIS

       gbkreg [options]

DESCRIPTION

       Kernel  estimation  of  conditional  moments.  Data are read from standard input as couple
       (x,y). The moments of y are computed on a regular grid in x. The kernel bandwidth, if  not
       provided with the option -H, is set automatically.

OPTIONS

       -n     number of equispaced points where moments are computed (default 64)

       -H     set the kernel bandwidth

       -S     scale the automatic kernel bandwidth

       -K     choose the kernel to use (default 0)

       0      Epanenchnikov

       1      Rectangular

       2      Gaussian

       -M     choose the method to compute the density (default 1)

       0      FFT (number of points rounded to nearest power of 2)

       1      discrete convolution (only with compact kernels)

       2      explicit summation (can be long)

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

       -v     verbose mode

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

       -h     this help

EXAMPLES

       gbkreg -M 2 < file
              compute the kernel regression of the entries in the second column of 'file' vs. the
              entries  in  the first column. If more data columns exist in file they are ignored.
              Explicit summation method (slower) is used.

       gbkreg -02 < file
              compute the kernel regression of the standard  deviation  of  the  entries  in  the
              second column of 'file' vs. the entries in the first colum
