RANKSORT(1) |STAT November 28, 1986
NAME
ranksort - rank order columns
SYNOPSIS
ranksort [-r] [-l lines]
DESCRIPTION
_▶08◀r_▶08◀a_▶08◀n_▶08◀k_▶08◀s_▶08◀o_▶08◀r_▶08◀t reads the lines from the standard input and rank orders each
column. Blank lines are ignored. Ties share the ranks, so if the
13th and 14th ranked numbers are equal, then each will be assigned the
rank 13.5.
_▶08◀r_▶08◀a_▶08◀n_▶08◀k_▶08◀s_▶08◀o_▶08◀r_▶08◀t is used on data when the assumptions for procedures like the
normal theory Pearson correlation coefficient are suspected to be
false. Under such conditions, the Spearman rho rank order correlation
coefficient is more appropriate. The Spearman rho is equal to the
Pearson calculation on the data converted to ranks. The normal theory
(F or t) significance test of the correlation coefficient is a good
approximation to the two tailed test of the rank order correlation
when the number of pairs is greater than 10. For smaller samples, a
table should be consulted.
OPTIONS
-l lines
Set the maximum number of lines to be read.
-r Reverse the order of the rankings. By default, rank orderings
correlate with input data so that smaller numbers get smaller
rank order values.
