| Format: | The course will
consist of two weekly 2 hour lectures and weekly homework
assignments. Occasionally, the 4th lecture hour on Thursday will be devoted to special topics, on which you will not be tested (except possibly for extra credit). Lectures will be mostly in person, with occasional pre-announced lectures on zoom The links for the Zoom lectures are posted on Canvas (go to Zoom in the left hand menu). Zoom lectures will be recorded. In person lectures will be recorded if LOW 205 is set up for Panopto recording; otherwise they will not. Slides will be posted on the handouts/Course notes page ahead of the class; during lectures I will use these slides as background, plus a virtual whiteboard, with GoodNotes. After class, the annotated slides will be posted on Canvas (go to Files/lecture notes). |
| Participation: | Attendance is not mandatory. However,
class participation is important and therefore it will be part of your grade. By class participation I mean more than just being
in class; you're expected to actively participate, either by asking
questions (the easiest) or by answering my questions and my invitations
to comments. Bonus participation points for selected answers on the discussion board may be awarded.
This year for the first time, we will try the following in-class exercises, which will count for participation. Occasionally, we will hand out a sheet of paper with short exercises and questions. You will have 5-10 minutes to work on them. At the end of this period, you can hand in your work or not. If you hand it in, there are the following benefits: you get feedback on it, AND it is equivalent to answering or asking a question in class, hence it adds to your participation points. It does not matter if you were correct or not in your answers, since this work is counted for participation only. How much participation is enough? Once a week on average is plenty. |
| Assignments: | Typically
assignments will be posted on the web (usually) on
Thursdays and will be due before class (usually) the following Thursday. The homework should be submitted as a single pdf file. We do not grade homework answers that are in the code.
The homeworks will consist of problems and short programming assignments. It is important to turn in your homework timely. First, because homework is a component of learning the new material. New lectures will build on past lectures as well as past homework results. Second, fair grading requires fair conditions for everybody. You are allowed to be late with your homework twice with no penalty. Further late homework will be penalized by up to 50%. No late homeworks are accepted once the solutions are out or the graded homework returned (this happens typically one week after the homework due date). Programming assignments:A typical programming assignment is: generate some data from a given distribution, do some processing, plot the results, draw conclusions. You will have to implement the data generation and processing. The programming language is your choice, and you are free (and encouraged!) to use library functions, but you have to write the code for the algorithms that are the subject of the course. For example, you are not expected to implement your own random number generator, but you will have to write code (that will use the random numbers) to simulate a dice roll. You will implement the formula for mean and standard deviation even if the software you are using has a built-in function for that. Occasionally, you may be required to submit the code you used for the programming assignments. This should not be in the same file with the homework, but submitted separately. We will not grade or debug your code, but we will do random checks to see if the code indeed does what it's supposed to do.
Python and Matlab. We will offer some support for those of
you who want to learn one of these languages while taking 391. The TA
will offer a pyton tutorial, and a short intro to Matlab will be
posted. Matlab is very easy to learn on your own, and is awesome at
making plots; however it is not available for free. Python is very popular overall, and also very easy to
learn. Making plots is comparatively less easy, but the package
matplotlib (which emulates the Matlab plotting capabilities) is some help.
Other homework problems will require calculus and easy arithmetic (in addition to what you learn in this class, of course). Both literal and numeric answers should be brought to their simplest form for full credit, and to allow you to fully appreciate the result. Math topics you should review: set theory, combinatorics and counting, taking derivatives and their meaning , integration (integration by parts, elementary properties of integration, primitives of common functions), elementary multivariate calculus and matrix operations. If there is need, tutorial sessions can be arranged for any of these topics.

| Teamwork: | Students are encouraged to talk to each other, to the TA, to the instructors, or to anyone else about any of the assignments. Any assistance, though, must be limited to discussion of the problem and sketching general approaches to a solution. Each student must write out her or his own solutions to the homework, including the code. We may use plagiarism detection software. Discussion board do's and don'ts: It is okay to ask clarifications about a homework question; i.e. "what does the question mean?" on the discussion board. It is not okay to ask "how do I solve this question?". For example, often we see "what number do I plug into formula (5) to solve Problem 1, a?". Both asking and answering such a question is inappropriate collaboration. |
| Regrading: | If you have reason to believe your homework was not graded correctly, please bring it up with the TA no later than a week after the homework grade is posted. |
| Grading: | The grade in STAT 391 this spring will be 5-10% participation, and the rest homework, possibly including a larger homework that we will call a project. I am considering having an optional oral exam (Details will be decided later, depending on the interest for this exam.) |
| Prerequisites: | A class in multivariate calculus (partial derivatives, multiple integrals, matrix algebra). A class in probability, including conditional probability and independence. Ability to write simple programs in order to do the homework. Ability to reason mathematically, to read, understand and discover proofs. Here is a list of the calculus topics we typically use. |
