Yes Risk Analysis is what Primavera has now titled what was previously known as Pertmaster. I believe they changed the name starting with current release version. Let's just hope they stick with this name and not change it every other release like they tend to do with the Enterprise Application.
When I went to school Risk Analyis was not just monte carlo on PERT ? Which is what I think PERTMASTER does. It seems to me like the Oracle take over of Primavera had added a whole new level of complexity to things which were nto that complex to begin with
