The experiment is to generate a random sample X1, X2, ..., Xn of size n from the Pareto distribution with shape parameter a. The distribution density is shown in blue in the graph, and on each update, the sample density is shown in red. On each update, the following statistics are recorded:
Statistics U and V are point estimators of a. On each update, the empirical bias and mean square error of each estimator are recorded in the second table. The parameters a and n can be varied with scroll bars.
This experiment illustrates the common point estimators that are used for the Pareto distribution, based on the method of moments and maximum likelihood. In particular, the experiment illustrates the concepts of bias and mean square error. For more information on the mathematical analysis, see

To add the applet to your web page, insert the following in the html file, at the point where you want the applet to appear:
<applet code="edu.uah.math.experiments.ParetoEstimateExperiment.class"
archive="ParetoEstimateExperiment.jar" width="600" height="400"></applet>
The jar file and the html file must be in the same folder.
This width and height dimensions are simply suggestions and can be varied. Generally, components such as graphs and tables expand and contract proportionally, while components such as buttons, scrollbars, dice, and coins are fixed in size.
