gbker2d 6.0.beta2                                 October 2018                                        GBKER2D(1)

       2D  kernel  density  estimation on an equispaced grid. Data are read from standard input as couple (x,y).
       The kernel bandwidth if not provided with the option -H is set automatically. Different bandwidths can be
       specified for x and y.

              compute the kernel on an equispaced grid 10x20 using a rectangular kernel

-n     number of points where the density is computed (default 10) use comma  (,)  to  specify  different
              values for x and y components

       -H     set  the  kernel  bandwidth  explicitly;  use  comma  (,)  to specify different values for x and y
              components

       -S     scale the kernel bandwidth with respect to euristic 'optimal' value;  use  comma  (,)  to  specify
              different values for x and y components

       -K     choose  the kernel to use: 0: Epanenchnikov 1: Rectangular 2: Silverman type 1 3: Silverman type 2
              (default 0)

       -D     switch off data de-variation procedure

       -v     verbose mode

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