Hey everyone,
I've posted a revised answer key to problem set 7. The previous version
of the answer key stated that the stochastic component of a negative
binomail is,
Y| \eta \sim Negative Binomial(\theta \lambda_i)
\eta \sim 1/\theta Gamma(\theta)
But the *correct* stochastic component is (notice the change from \theta
to \eta in the Y|\eta portion)
Y| \eta \sim Negative Binomial(\eta \lambda_i)
\eta \sim 1/\theta Gamma(\theta)
I hope this did not cause any problems--
Cheers,
Justin
