PA 715 Students: Multivariate pdf visualization

I found some applets that may be useful.

From here, scroll down to the "Java Applets for Visualization of Statistical Concepts" link and then click on "Basics" and then "Bivariate normal distribution". An applet will open that allows you to change the attributes of the distribution, including the degree of correlation between X and Y. We may return to this site later in the course, as it appears that there are lots of good visualization tools here.
