NAME

       gbhisto2d - Produce 2D histogram from data

SYNOPSIS

       gbhisto2d [options]

DESCRIPTION

       2D  histogram  on  a  regular grid. Data are read from standard input as couples (X,Y). If
       data are treated as continuous, equispaced bins are built  and  their  center  coordinates
       together  with the required statistics are printed. For discrete variables, bins are built
       directly from the given variables. Transition matrices (option -M 5 and -M 8)  have  final
       states  across  the  rows. In case of continuous variables it is also possible to consider
       rectangular matrices.

   Options :
       -M     choose the statistics to print for each bin (default 0)

       0      occurrences number for continuous binned variables (*)

       1      relative frequency for continuous binned variables (*)

       2      empirical density  for continuous binned variables (*)

       3      occurrences number for discrete symmetric variables (bins{X}=bins{Y})

       4      relative frequency for discrete symmetric variables (bins{X}=bins{Y})

       5      transition matrix  (X=>Y) for discrete symmetric variables (bins{X}=bins{Y})

       6      occurrences number for discrete asymmetric variables

       7      relative frequency for discrete asymmetric variables

       8      transition matrix  (X=>Y) for continuous binned variables (*)

       -n     number of equispaced bins where the histogram is computed. For output  marked  with
              (*),   use comma ',' to specify different values for x and y coordinates.  (default
              10)

       -v     verbose mode

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

       -h     this help

EXAMPLES

       gbhisto2d -n 20 < file
              compute a 2D histrogram using 20x20 bins.

       gbhisto2d -M 8 -n 4 < file
              compute transition matrix on equispaced bins for continuous variables.
