The spreadsheet, including formulas, for our sample proportion estimation example is available here if you have a spreadsheet program that reads SYLK files.
If you have a spreadsheet that reads SYLK files you can play with the parameters and simulate Bayesian prediction in a dynamic linear model.
You can also see a real-time simulation of Bayesian prediction in a dynamic linear model. Compare with best mean square prediction in an autoregressive model.
You can run a Monte Carlo estimate of a Poisson parameter. It is the Bayes estimate of the mean q of a Poisson distribution assuming squared error loss and a heirarchical prior of gamma distributions. See the Poisson gamma heirarchy in Lehmann and Casella, Theory of Point Estimation, for details.
