**Click on the text like “Week 1: Jan 20 – 24” to expand or collapse the items we covered in that week.**

I will fill in more detail and provide links to lecture notes and labs as we go along. Items for future dates are tentative and subject to change.

**In class**, we will work on:- Discuss syllabus, overview of course
- Review of prerequisites

**After class**, please do the following:**Register for GitHub**here if you haven’t already; I will ask you to provide your GitHub user name in the questionairre below.**Fill out**a brief questionnairre (if you are taking two classes with me, you only need to fill out this questionairre once)**Fill out**this brief poll about when my office hours should be held (if you are taking two classes with me, you only need to fill out this poll once)**Sign up**for our class at Piazza (anonymous question and answer forum): https://piazza.com/mtholyoke/spring2020/stat343**Reading**- Review the prerequisite material from probability and calculus. If there are any topics from probability that you don’t have memorized, please start memorizing them. This will make the rest of this class go much more smoothly for you. If you have any questions on this material, please don’t hesitate to ask me in office hours or on Piazza. I am happy to help with this material.
- Over the next 1 or 2 classes we will cover material from Chapter 6 of the text. Give those sections in the book a brief skim.

**Homework 0**due 5 pm Mon, Jan 27

**In class**, we will work on:- Wrap up any remaining probability examples from last class
- Define the \(t\), \(F\), and \(\chi^2\) distributions; this material is in Chapter 6 of Rice. Lecture notes: pdf
**Note that there is a minor error in the lecture notes that we did not make in class:**on page 5, the denominator should be the square root of a chi squared random variable divided by its degrees of freedom. Basically, we need to take the square root of the square of the denominator to see that we have a t-distributed random variable. - Lab 01. See labs page for solutions.

**After class**, please:**Reading:**Over the next few classes we will cover material from Sections 8.1, 8.2, 8.3, and 8.5 of the text. Give those sections in the book a brief skim.**Homework 0**due 5 pm Mon, Jan 27

**In class**, we will work on:- Start on maximum likelihood estimation.

**After class**, please:**Reading:**Over the next few classes we will cover material from Sections 8.1, 8.2, 8.3, and 8.5 of the text. Give those sections in the book a brief skim.**Homework 0**due 5 pm**today**, Mon, Jan 27

**In class**, we will work on:**Quiz**on probability background. This will be very similar to the examples from Wednesday Jan 22 and HW 0. Please memorize everything on the “Topics from probability” document linked on the Resources page, and know how to use it. You only need to know the informal statement of the Central Limit Theorem.- More on maximum likelihood estimation:

**After class**, please:**Reading:**Continue working through Section 8.5. Also give Section 8.4 a brief skim.**Homework 1**due 5 pm Wed, Feb 5

**In class**, we will work on:**After class**, please:**Homework 1**due 5 pm Wed, Feb 5**Reading**: Over the next few days, we’ll explore using Newton’s method to numerically optimize the log-likelihood function. Wikipedia is a reasonably good source; you could give the following a skim:- Remind yourself about how Taylor’s theorem works by skimming the [Wikipedia article] and/or looking at the last page of the review of topics from calculus posted on the Resources page of the course website. We’ll review this at the beginning of class on Wednesday too.
