.TH PAIR/BIPLOT 1 "March 5, 1985" "UNIX|STAT 5.0" "UNIX User's Manual"
.SH NAME
pair, biplot - paired points analysis
.SH SYNOPSIS
.B pair
[options]
.SH DESCRIPTION
.I Pair
is useful for analyzing paired data by providing
summary statistics and scattergrams.
It can also be used to analyze a time series
or any ordered series of data.
.I Pair
reads pairs of points (two points per line)
from the standard input and without options
provides statistics on the first variable (X), the second (Y),
and their difference.
If only one datum is on each line,
then
.I pair
will supply the datum number (1 to N) as the first variable
and use the datum as the second.
.I Biplot
has the same capabilities as pair, but without options
prints a bivariate plot.
If less than ten points plot to a coordinate, the number
of points is plotted, otherwise a star is plotted.
.SH OPTIONS
.TP
.B -b
asks for a bivariate plot (same as -p).
.TP
.B -c char
sets the character plotted to \fIchar\fP.
This can be useful to compare two plots;
plot each with a unique character on transparencies
and overlay them.
.TP
.B -h N
sets the height of the plot to N lines.
.TP
.B -p
asks for a bivariate plot (same as -b).
.TP
.B -s
asks for summary statistics.
.TP
.B -w N
sets the width of the plot to N characters.
.TP
.B -x NAME
sets the name of the first variable to NAME (default is "Column\ 1").
.TP
.B -y NAME
sets the name of the second variable to NAME (default is "Column\ 2").
.SH LIMITATIONS
For plots, the number of points is limited to some large number,
perhaps 1000.
.SH SEE\ ALSO
unixstat(1), dataplot(1), regress(1)
