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
