JAVA APPLETS For Visualizing Linear Regression*:

• Drawing a Regression Line by "Eye" draw a line on the scatterplot.  MSE error is computed.  Check the minimum MSE and see how close you can get.  Click the box to see the least squares line.  This applet is part of the Rice Virtual Lab in Statistics. (Note:  Netscape 4.06 or better is required for Java 1.1)
• Guessing Correlations - a fun "game" to show the relationship between correlations and scatterplots.  Part of the CUWU Statistical Program at Illinois-Champaign-Urbana.
• Influence in Regression - see the effects of adding an outlier to a least squares line. (Webster West - S. Carolina).
