Danny wrote a few probability distribution functions included into an Ocelet file :
These functions are part of a structure for usage convenience and modularity.
That Ocelet file is part of a
Test_Random Ocelet model that shows how one can use the structure and the functions it contains.
You can import that model to learn how to use the functions, and then just copy the
RandomDistributions.oclt file into the
oclt folder of your own model. You may then be able to use the
gaussian() function to generate observations for example.
Here is the link to obtain the
Test_Random model : http://ocelet.fr/ocws/files/models/Test_Random.zip
Hope this helps
