On page 405 in Chapter 13 Task 5 Subtask e might be an error.
In this task the bayesian network X -> Y -> Z has to be implemented in a figaro program.

Change the prior for Y given that X is true to
Beta(2, 1), and the prior for X given that Y is true to Beta(1, 2).


In my opinion X is independent from the state of Y and therefor the task should be:

Change the prior for Y given that X is true to
Beta(2, 1), and the prior for Y given that X is false to Beta(1, 2).

Hi,

I think that there is an error on figure 4.16 page 125. It is marked 0.1 for the density, but it should be 0.01. It is 1/(150-50). The text also states 0.01.

Hi,

There is an error on page 151, figure 5.11. It must be "Prints quickly" and not "Prints quality".

Chapter 5

1) page 164, "every variable will have a copy of the unary potential in table 5.2" should be table 5.1

2) page 169, in the summary the first item is wrong in two places. "Symmetric relations produce directed dependencies" ... no it is the opposite which makes the next statement also wrong.

In exercise 1 of chapter 4. I think you have to specify that there are 2 players.
