This class will cover finite sample theory of statistical inference – including estimation, hypothesis testing, and confidence intervals – and elementary large sample theory. Specific topics (depending on time may or may not be able to cover all but aim to) include: statistical models; sufficiency; applications to exponential families, group families, and nonparametric families; minumum risk unbiased estimation; minimum risk equivariant estimation; Cramer-Rao Inequality; loss and risk functions; Bayes estimation; minimax estimation; admissibility; shrinkage estimators; Neyman-Pearson theory for hypothesis testing; confidence intervals; uniformly most powerful test and uniformly most accurate confidence intervals; asymptotic relative efficiency; maximum likelihood estimation; Wald, score, and likelihood-ratio tests; delta method; asymptotic distribution of quantiles and trimmed means.

Complete required reading in textbook

Complete weekly homework (posted on Sakai)

Midterm (in class on March 1)

Final (9:00-12:00 on May 1)

Homework (25%) + Midterm (25%) + Final (45%) + Participation (5%). Participation includes lecture attendance, lecture scribing and discussion participation on Sakai.

**Late homeowork policy**: Homework turned one minute late but on the due day will be counted as one day late. The next day will be two days late, etc. No homework more than two full days (48 hours) late will be accepted. Each late day will result in a one-level down-grade (10% off) of that homeowork.**Regrade requests**on Gradescope within 2 daysDrop the HW with the lowest score for final grade

**Exam policy**: no makeup exams

I understand that the electronic recording of notes might be important for class and so computers will be allowed in class. Please refrain from using computers for anything but activities related to the class. Phones are prohibited as they are rarely useful for anything in the course. Eating and drinking are allowed in class but please refrain from it affecting the course.
