public class BivariateNormalExperiment
extends Experiment
implements java.io.Serializable

This experiment generates a point (X, Y) from a bivariate normal distribution with mean (0, 0). The point is shown graphically as a red dot in the scatterplot, and the coordinates are recorded on each update. The distribution regression line is shown in blue in the scatterplot, and the sample regression line is shown in red. The density function and moments of X and of Y are shown in the distribution graphs, and the moments are given in the distribution tables. The last table gives the distribution and sample correlation. The distribution standard deviations and correlations can be varied with scroll bars.
