A "pop-up choice" menu will appear below when the applet is finished loading. Click and hold the choice menu and choose a dataset. After a slight delay, a window will open containing a histogram and cross validation plots. If you wish to enter or paste in your own data, choose "Enter Data." A window will open for you to enter your data. You should have one data point per line. The graph on the left shows the cross-validation values of 30 bin widths for the value of the "lower limit of the first bin" specified on the right graph. The graph on the right shows the cross-validation values of 20 "lower limits of the first bin" for the bin width specified on the left graph. The lower the overall cross-validation, the better the histogram represents the data.
