We have in our hands (via the predictive posterior) the probabilities that Susy's GPA is less than any number between 0 and 4, given that we accept the normal model…

In Part I we had the simplest kind of model. We complicated it in Part II, built more structure in Part III, and today finally come to the most used…

The rules of logic are simple. Use whatever evidence you have, and no other, to figure the probability of a conclusion. These rules are all we need to understand what…

In thinking about what probability means, it's important to sort out what is contingent and what relationship contingent events have to causality. Contingency simply means that what is could have…
