2/5 HW 3 ANNOUNCEMENT For exercise 2, you may either assume that the sigma^2s are known (using an estimate from the data), or you may use an MCMC algorithm and fit the sigma^2s in addition to the thetas and mu. For exercise 3, you should assume that the sigma^2s are unknown.

2/2 If you were not in class today, please download the description of the final project.

2/1 TYPO in the R code for the schools example
In the sample.mu function, mu.post.var <- 1/(sum(rep(1,N)/(sigma.sq+tau.sq))) instead of mu.post.var <- sum(rep(1,N)/(sigma.sq+tau.sq)). Your class notes are correct. Click here for a revised version of the code.

1/29 Homework 3 is now available on the Homework page.
Note: The solutions for HW3 will be posted immediately after class on Tuesday, Feb. 7th, so that you have time to review them before the midterm exam. As a result, NO late homeworks will be accepted. In addition, keep in mind that we will not be able to return the homeworks before the midterm, so if you would like to compare your answers to the solutions, please make a copy of them before turning them in.
