NAME

       gbhisto - Produce histogram from data

SYNOPSIS

       gbhisto [options]

DESCRIPTION

       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.

OPTIONS

       -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
