# Introduction to Mathematical Statistics

## (Course Web Page and Syllabus)

## Spring 2020

Time: 3:00-3:50 MWF

Room: ECCR 135

## Instructor: Dr. Janos Englander

## Course content:

Examines point and confidence interval estimation. Principles of maximum likelihood, sufficiency, and completeness: tests of simple and composite hypotheses, linear models, and multiple regression analysis. Analyzes various distribution-free methods. Prereq: MATH 4510 or APPM 3570, and Calculus 1-2-3. Same as APPM 4520.

## TEXTBOOK: "John E. Freund's Mathematical Statistics with Applications" (8th Edition)

### Important: The textbook should exactly (!) be the hardcover or the paperback shown here: CLICK . It should NOT be the international edition, as it skips certain parts. However, the eTextbook is fine if the same as in this link. For example, the hardcover has these ISBN identifiers: ISBN-13: 978-0321807090 and ISBN-10: 032180709X.

## EXAM DATES:

**First MT: **TBA

**Second MT: **TBA

**Final: ** As scheduled by the Office of the Registrar, it will be on **Monday, May 4, 7:30 p.m.–10 p.m.**

Note: When students have three or more final examinations on the same day, they are entitled to arrange an alternative examination time for the last exam or exams scheduled on that day.

# FAQ:

- Where is the syllabus? A: This web page IS the syllabus.
- Is the final cumulative? A: Yes.
- Where are the HW from? A: From the textbook.
- Where is the funny accent from? A: Hungary.
- I cannot come to the MT because of health issues or family emergency. What to do? A: Please show me some documentation. I can offer you to skip the MT and calculate your grade based on the other factors, proportionally.
- Can I turn in the HW late? A: No. Sorry. But remember that the weight of a single assignment is very small.
- This class is for UG (4520) and Grad (5520) students together. What does this mean in practice? A: HW and exams are slightly extended for grad students. See below.
- I have an older edition of the textbook. Is it OK? A: Unfortunately, that can be a problem, because the HW might be different.
- Do we have to remember all those horrible formulas at the exam? A: A cheat sheet will be provided. Tables too.
- Do I have to write to the instructor because I will skip a class or two? A: No.

## Enrollment questions:

Please see the Registrar's web page, or call their office. If you still have problems, then see Tiffany at the Math. Dept. Office, please.

## How to reach me/office hrs:

Office: MATH 324.

**Office hours**: Monday and Friday 12-1.

Phone: 303-492-4846 (with voice mail)

EMAIL: firstname.lastname@colorado.edu

(Please refrain from using "Hey Professor" as a greeting.)

## Help Lab:

The Undergrad Resource Center (a.k.a. Help Lab) is a valuable resource.

Please check the hours of operation at **http://math.colorado.edu/marc/**

**Material to be covered:** We begin with a brief overview of Chapters 1-7 and continue with Chapters 8, 10-14, and some of Chapters 15 and 16, if time permits.

### Prereqs and a warning:

MATH 4510 is a prereq, and so is Calc 1-2-3, in particular **it is assumed that students are familiar with double and multiple integrals.**

**Homework:** Homework assignments will be given weekly.

**How 5520 students are different:** Students enrolled into MATH/APPM 5520, will have to do extra homework problems as well as extra problems on the tests.

**Exams: **There will be two in class midterms and a Final.

# Grading:

Grading will be based on attendance, homework and exams, as follows:

- Attendance: 10%
- Homework: 20%
- Midterm 1: 20 %
- Midterm 2: 20%
- Final: 30%

My** grader** for this semester is Krisztina Dearborn, her email is **Krisztina.Dearborn@colorado.edu**

Please direct questions like "why did I loose 2 points here" to her.

## MIDTERM related STUFF:

IMPORTANT: *These two below were mid semester MT's. So only the first questions are relevant for our first midterm! However, we'll have an in-class practice MT.*

Solutions to an old Midterm: CLICK

Our first practice MT: CLICK

Solutions to MT1: CLICK The median was **81.5** for MT1.

Our second practice midterm before MT2: CLICK

## FINAL related STUFF:

Exercises for ML and N-P . (12.12 is the same as Pr 6 in the practice final, except theta_1>theta_0)

## Homework:

From Friday to Friday. (With some exceptions.) To turn in: in class.

### Important:

If you are a **graduate student**, then please put a huge "G" at the right top corner of your HW. Thank you. And of course, please try to write in a legible way. Typing would be even better :)
