SYNOPSIS
SUBROUTINE PLOTU(X,N)
DESCRIPTION
PLOTU(3f) produces the following 4 plots-- all on the same printer page--
1. data plot--x(i) versus i 2. autoregression plot--x(i) versus x(i-1) 3. histogram 4. normal probability plot In addition, location, scale, and autocorrelation summary statistics are printed out automatically on the same page.
These plots give the data analyst a quick first-pass check at some of the underlying assumptions typically made-- constant location, constant scale, no outliers, unautocorrelated data, symmetry, normality.
