SYNOPSIS
SUBROUTINE PLTXXT(X,N)
DESCRIPTION
pltxxt(3f) yields a narrow-width (71-character) plot of x(i) versus x(i-1). Its narrow width makes it appropriate for use on a terminal.
this type of plot (which is called an autocorrelation plot or a lag 1 plot) is useful in examining for autocorrelation in a sequence of observations.
uncorrelated data will produce an autocorrelation plot with no apparent structure; autocorrelated data will produce an autocorrelation plot with linear, elliptical, or other kinds of structure.
