### Replicating a Tweedie corrected experiment from Computer Age Statistical Inference

I have been attempting to replicate an experiment from Computer Age Statistical Inference by Bradley Efron and Trevor Hastie on page 411. In this experiment 100 datasets are populated normal random ...

### Is appropriate to use empirical Bayes (EB) in this way?

Background. I have data from a study where participants make a series of judgments (a series of decisions with a binomial outcome, either $y=1$ or $y=0$). I have a model of the underlying decision-...

### Hyper-parameter estimation for Beta-Binomial Empirical Bayes

I am reading a paper Illustrating empirical Bayes methods and in the paper the author uses method of moments to derive the value of an estimate. In equation 17 the author gives the following marginal ...

### Robbins estimate Empirical Bayes

From the compound sampling model where: $Y_i | \theta_i \sim Poi(\theta_i)$ The marginal distribution of $\theta_i$ is $G$, non-parametric. We get that the Bayes estimate of $\theta_i$ under ...

### Empirical Bayes Estimation

Suppose $X_i$ conditioned on $\mu$ is iid $N(\mu, \sigma^2)$ and $\mu$ is distributed as $N(\mu_0, \tau^2)$. Is there a way to estimate $\tau^2$?

### James-Stein Estimator with unequal numbers in groups

In the book Computer Age Statistical Inference the James-Stein estimator is introduced. Brad Efron runs through an example where batting averages are estimated from each players 90 at-bats. p_i\sim ...

### How is empirical Bayes valid?

So I just finished reading a great book Introduction to Empirical Bayes. I thought that the book was great, but building priors from the data felt wrong. I was trained that you come up with an ...

We can use an empirical Bayes framework to iteratively refine the least-squares fitting of some model $f$ parameterized by weights $\textbf{w}$. This can be done by presuming a Gaussian prior on the ...
