gbhisto 6.2                                         June 2021                                         GBHISTO(1)

       Compute  histogram  counting  the  occurrences  of  each value (discrete data) or binning the values on a
       regular grid (continuous data). Data are read from standard input. For discrete data,  values  and  their
       occurrences  are  printed;  For  binned  data,  the  bin  reference point and the relative statistics are
       printed. The type of variable and the statistics can be set with option -M.   The  binning  grid  can  be
       linear,  logarithmic  or  geometric. The bin reference point is the algebraic midpoint for linear binning
       and the geometric midpoint for log or geometric binning. The reference point can be  moved  using  option
       -S. Set it to 0 for the lower bound or to 1 for the upper bound.

-n     number of equispaced bins where the histogram is computed (default 10)

       -w     min,max set manually the binning window

       -M     set the type of output (default 0)

       0      occurrences number (continuous binned variable)

       1      relative frequency (continuous binned variable)

       2      empirical density  (continuous binned variable)

       3      occurrences number (discrete variable)

       4      relative frequency (discrete variable)

       5      CDF (left cumulated probability; continuous binned variable)

       6      inverse CDF (1-CDF; continuous binned variable)

       -B     set the type of binning (default 0)

       0      linear

       1      logarithmic

       2      geometric

       -S     set the bin reference point (default 0.5)

       -r     set the ratio for geometrical binning  (default 1.618)

       -t     print the histogram for each imput column

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

       -v     verbose mode
