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.

print the quantile (interpolated) associated with the value |
|||
|

|
-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) |
|||
|
