DESCRIPTION
plotxx(3f) yields a one-page printer plot of x(i) versus x(i-1).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.
