The fourth and last step of the program is the choice of the elements
to include in the report. Some elements such as **all the data
points from the plots**, the **ability estimates** or the **test
of local independance** can take a lot of pages in the report, it is
recommended to activate them only if necessary.

After this step, the estimation process begin. While the estimation is
running, *Excel* will not be usable. The time of the estimation
depends on the number of subject and item, the model and the computer
speed. For a few thousands subject and ten items, the estimation
should not take more than ten seconds for binaries items and two or
three minutes for five options items on a recent computer.
