Course description.

In this course we will cover core topics in point estimation, hypothesis testing, and Bayesian statistics. Highlights include the Cramer-Rao bound, the Rao-Blackwell theorem, the Lehmann-Scheffe theorem and the Neyman-Pearson lemma.

In particular, students should be comfortable with conditional expectation, the law of large numbers, and the central limit theorem.

Other suitable references are:

Introduction to Mathematical Statistics, Hogg, McKean, and Craig. (Used last year)

Statistical Inference, Casella
and Berger (Used in previous years)

Mathematical Statisitics, Shao

Theory of Point Estimation, Lehmann and Casella

Testing Statistical Hypothesis, Lehmann and Romano

This course will also have a minor computing component. We will have the chance to use the free statistical software R. It can be downloaded here. A short introduction to R can be found here. Knowledge of R will not be required on examinations. However, there may be a few R homework assignments.

Homework 1: Due January 31

solution

Comments:

Updated Question 1; it is a better question now and also added the missing assumption of independence.

For Question 2, you do not need to know anything fancy about the distribution of a sum of independent uniforms, the reason being is that you only need to know the cdf of the sum up to value 1, and no more no less. Use induction.

For Question 5b, there was a missing term in the event, this is now corrected.

For Question 5e, there was a typo, it should have said Zk = Finverse(Vk); this has been corrected in the pdf file.

For Question 7, the pdf for the multivariate normal is provided.

I encourage you to typeset your solutions using LaTeX. For you reference here is a LaTex file that can be used to generate this homework .

Comments: In Question 1, there should be a negative sign was missing in one of the equations that defined symmetric. This has been corrected.

Comments:

In Exercise 2, the definition of T is the sample sum; this was left out in the previous version, and is now corrected.
