gbquant 6.1                                        March 2019                                         GBQUANT(1)

       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. With option -Q each entry is replaced with the quantile range it belongs to, with
       respect to the distribution obtained from the entries in its column.

       gbquant -W 0 -w 0.1,0.9 < file
              print the rows whose fields are all in the center deciles.

       gbquant -q 0.5 < file
              print the median of the observations in 'file'.

       gbquant - Print quantiles of data distribution

-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-Q     replace each element with the quantile range it belongs to

       -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
