I gave a talk on Sherpa's methods for calculating parameter confidence last month at SciPy 2011. This presentation is formatted as a sphinx generated web page similar to python4astronomers. The page includes a benchmark fitting example, complete with Python code that describes Sherpa's confidence method, simulations, and MCMC methods uing pyBLoCXS.

Tom is giving an "Advanced Sherpa" talk at CIAO Workshop. Talk contains a lot of good hints on using Sherpa Python.
