Title: Joint Gaussian probability plot program. [ECP2D, plots ellipses of constant likellihood, for CDC 7600]
Abstract: The analysis of joint-Gaussian distributions of two variables can be aided greatly by meaningful graphical techniques. The program described performs such a task. Two elliptical equi-probability contour plots of the probability density function are produced, one using statistics from the raw data and the other using normalized (zero mean, unit variance) variables. Several separate data sets of the same variables may be plotted, for example, to compare estimators. The techniques discussed for interpreting the plots enable the user to gain insight into the statistical information being displayed. 8 figures, 4 tables.
