# gbquant(1)

Print quantiles of data distribution

## 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. 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.

## 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**

- **-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

## EXAMPLES

- 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'.
