NAME

       gbquant - Print quantiles of data distribution

SYNOPSIS

       gbquant [options]

DESCRIPTION

       Print  distribution  quantiles.  Data are read from standard input. If no -x or -q options
       are provided, a quantiles table is plotted. The number of quantiles can be chosen with -n.
       The  option  -x #1 prints the quantile associated with the value #1, while -q #2 print the
       value associate with the quantile #2. Of course #2 must  be  between  0  and  1.  Multiple
       values  can  be  provided  to  -x  or  -q,  separated  with  commas. With -w #1,#2 all the
       observations inside the quantile range [#1,#2) are printed. If more columns  are  provided
       with  option  -t, the specified action is repeated on each column. Without -t, columns are
       pooled unless -w is specified, in which case all rows whose first element  is  inside  the
       range  are  printed.  A different column for sorting can be specified with option -W. If 0
       is specified, the cut is applied with respect to all columns

OPTIONS

       -n     number of quantiles to print (default 10)

       -x     print the quantile (interpolated) associated with the value

       -q     print the value (interpolated) associated with the quantile

       -e     print the (asymptotic) error for -x or -q; doesn't work with -t

       -w     print observations inside a quantile windows

       -W     set the column to use (default 1)

       -t     consider separately each column of input

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

       -h     this help

       -v     verbose mode
