NAME
vincent - vincentizing of data from files
SYNOPSIS
vincent n file1 file2 ...
DESCRIPTION
_▶08◀V_▶08◀i_▶08◀n_▶08◀c_▶08◀e_▶08◀n_▶08◀t is useful for looking at trends over time/trials in
data. _▶08◀V_▶08◀i_▶08◀n_▶08◀c_▶08◀e_▶08◀n_▶08◀t takes as arguments a series of files of
numbers. The filename ``-'' can be used to read from the
standard input. For each file, _▶08◀v_▶08◀i_▶08◀n_▶08◀c_▶08◀e_▶08◀n_▶08◀t divides the series
of numbers into _▶08◀n equal parts using linear interpolation and
prints the means for each part (called a vincentile). For
example,
vincent 5 foo bar
will print the means for each fifth of the files "foo" and
"bar." For each file argument, _▶08◀v_▶08◀i_▶08◀n_▶08◀c_▶08◀e_▶08◀n_▶08◀t prints the number of
points read in from that file, the name of the file, and the
means for each of the ``vincentiles'' you have asked for.
_▶08◀V_▶08◀i_▶08◀n_▶08◀c_▶08◀e_▶08◀n_▶08◀t is useful for comparing series of different lengths.
This was its original use in mathematical psychology some
decades ago. See the Handbook of Mathematical Psychology,
by, among others, Pat Suppes for a thrilling discussion.

The program is named after S. B. Vincent who suggested a 4-
tile version of the procedure. You can look up the original
source in his 1912 paper, The function of the vibrassae in
the behavior of the white rat. _▶08◀B_▶08◀e_▶08◀h_▶08◀a_▶08◀v_▶08◀i_▶08◀o_▶08◀r _▶08◀M_▶08◀o_▶08◀n_▶08◀o_▶08◀g_▶08◀r_▶08◀a_▶08◀p_▶08◀h_▶08◀s.
