2. Click on "Example 1" button. than the "Data" button to see the data.

3. The data need to be send to the computer for analysis. Click on the "Mapping" button to include the groups you want.

4. Click on the "Calculate" button to enter number of parameters. For example, for a Poisson model, you should enter '1' for that Poisson model has 1 parameter. If you don't enter any number, the default used is 0.

You'll see a message like below if you don't type in any number.


5. Now you're ready to see the results. Just click on the "Result" button.



If you'd like to include some other group(s) or remove the current groups and start over, simply go to the Mapping button and take the groups you want.
