Assignments
This course has 4 midterms, 1 final, 1 replication, 1 project, and 5 Stata homeworks. All the assignments will be carefully described in the announcements page. Here is a brief description:
Question 1 will describe a situation, and ask several questions. The questions will be given to you in advance, but the situation is a surprise.
Question 2 refers to a scientific paper. The paper and the questions will be given to you in advance.
Question 1 is similar to question 1 in the midterms, however, both the situation and the questions will be a surprise (although by the end of the semester you will be able to guess what will be asked).
Question 2 is an essay. You will be given a situation, and you will describe how you would develop a research project about it. The situation will be a surprise, but you will be able to see the examples used in the previous years.

Each midterm has two questions.Question 1 will describe a situation, and ask several questions. The questions will be given to you in advance, but the situation is a surprise.

Replication
The replication assignment is a replication of the same paper we were studying in the midterms using Stata. You will download a data set, clean it, and do everything the author did, hopefully achieving similar results.Project
The project is a 5 to 10 page essay criticizing the paper we studied in the midterms and the replication. It begins with a description, and then continues to a critique.Stata homeworks
The Stata homeworks are short. The point is for you to practice programming using this software.Weights

Make up exams and late homeworks
There are no make-up exams, and the rules on late homeworks are very strict. If for any reason you missed an assignment, remember that the lowest grade will be dropped. This is the reason we drop the lowest grade in the first place, so no complaints! When an assignment is posted, there will be an update in the announcements page with all the rules concerning that assignment.
Lectures and sections
Lectures follow the notes, which you can download in the download page. You will see that the notes have several gaps in them which you must fill in class. Hence, though lectures are not mandatory, you must make sure that you get the notes somewhere. A lot of the material in the notes cannot be found in the book, so you must take action to complete the notes if you missed class.
Stata labs are not mandatory. However, they were carefully planned so that the material and examples fit perfectly with the course, and you can't get this anywhere else. If you must miss a lab, take measures to remedy that. Computers in the Stata labs are limited. Students that are registered to a particular section have priority. If you have Stata in your laptop, you can bring it to the section.

Stata
The university has Stata installed in all lab computers. You can also purchase an inexpensive Stata license in this link. If you decide to buy Stata, buy the IC version or better. Do not buy the "small Stata" version, because it won't be able to handle most data sets in this course.
Book
The textbook is "Statistics," by David Freedman, Robert Pisani, and Roger Purves. It is published by W.W. Norton. Be sure to buy the 4th. edition, 2007.
The book is complementary to the class notes. You can download the notes in the download page, and they are made so that you come to class with them, and fill out the gaps there.
The book was chosen because of the brilliant way in which it approaches the material. It goes to the heart of the issues, and is very explicit in exposing the problems with the techniques. Read more about the book here.
You can buy it directly from the editor: http://books.wwnorton.com/books/978-0-393-92972-0/
but you may get a better deal at other online retailers such as Amazon.com, Barnes & Noble, Borders, etc. The link for Amazon is:

Resources
Office hours. There are many office hours spread through all days in the week. You can see the schedule in the calendar page. You can bring all your questions to the regular office hours, but I recommend that you check the Contact the TAs page to see in what that TA specializes. After the assignments are handed back, the TAs that graded the assignment hold grading office hours. Bring your grading questions to them.
Class Plan. This page contains a very detailed plan of the entire course, including assignment due dates. I update it often to make adjustments to the plan as the course progresses, and to write comments. You can use this page to prepare for classes in advance, as a review guide, and as a detailed account of the material that will be required in the exams.
Forum. The forum is the go-to place when you have questions, especially if you need them answered soon. Before you e-mail anybody, check the forum. Somebody may have already posted the same question, and received an answer. If not, post the question there. There are TAs especially assigned to monitor the Forum, answer questions, and contact me or the other TAs when they don’t know the answer. I also check the Forum frequently, monitor most of the TA answers, and often answer questions there. You do not need to post under your name, you can create a dummy account if you feel embarrassed. If you e-mail us questions that we think will be of general interest, we will likely ask you to post if there anyway, so save everybody’s time and go there directly. Want to know how to post in the forum? Read this.
Live Help Events. These are forum office hours. During those events one of the TAs will be monitoring the forum, and answering questions as they appear. During the Live Help events your questions will be likely answered on the spot, and you don’t even have to leave your home.
E-mail. You should e-mail me or one of the TAs when your question is not of general interest. There are special rules concerning e-mails, and you can read them in the Contact us page.

If throughout the semester ANY student feels either depressed, overly anxious, desperate, hopeless, angry, or neglected, be it related to this course or not, please reach out. Write to me or come meet with me at the office hours.
