### Admissible decision rule is always Bayes for some proper prior

I think I am able to visualize this graphically, but can't think of how to write this out. Some other literature online suggests drawing a picture, but I was looking for a concrete proof. I started ...

### Calculating the probability of 31 of 628 items are sampled (no replacement) more than 10x amongst 150 participants drawing 50 items each

I am sorry for having to ask a simple probability question, but I have been thinking about it for weeks and an extensive google search has given no answers. I have a group of 628 questions. 31 ...

### Sequential Inference And Evidence (Jaynes 2003): Is it valid? Is it used?

Exploring the work of ET Jaynes, Probability Theory (11th Printing 2013) has led to consideration of the technique he identifies as Sequential Inference (p. 96); where the evidence, in decibels, ...

### Why do Bayesian Networks use acyclicity assumption?

Actually, this question is more or less a duplicate of the one which I have asked on math.stackexchange two days ago. I did not get any answer there but I think now here is a better place to ask ...

### Closed form solution for posterior with scale mixture normal prior

Is there a closed form for the posterior mean and variance of an observation drawn with known measurement error if the prior is a scale-mixture normal? To be more clear, here's the implicit model: ...

### Probability of a random outcome given a sample size

Say you gave an IQ test to a random sample of $n$ people, but instead of having the actual test results, you have only the normalized data for this sample (mean=0, $\sigma$=1). What is the ...

### General Statistics Problem: Identifying trends in data

I apologize in advance if this question is overly general. I have a practical solution, which isn't very elegant, and having only a little bit of experience with statistics, am hoping for general ...

### Why doesn't ML point estimate equal MAP point estimate even though I'm using uniform prior?

I asked a previous question about why the ML and MAP estimates are the same when using a uniform prior (How does a uniform prior lead to the same estimates from maximum likelihood and mode of ...

### Elementary statistics for jurors

I have been summoned for jury duty. I am conscious of the relevance of statistics to some jury trials. For example, the concept of "base rate" and its application to probability calculations is ...

### Optimal software package for bayesian analysis

I was wondering which software statistical package do you guys recommend for performing Bayesian Inference. For example, I know that you can run openBUGS or winBUGS as standalones or you can also ...
