Econometrics: Final grades

Next table summarizes the final grades, including the result of the June 5th exam:

In this link you can find the exam, with some short handwritten explanations. If some component of your grade looks wrong, please send me an e-mail and I will revise the case.

Teaching you has been both, a real challenge because of the lenguage, and a pleasure because of your sympathy and excellent attitude. Sadly I am not so satisfied with my own performance, as my teaching sometimes fell below the standards that I set to myself. Please accept my sincere apologies for these shortcomings.

If I can do something for you, do not hesitate in telling me. Good luck!

Econometrics: Partial grades

Next table summarizes three partial items in your grade: short tests, personal work (your essay about the Campus Crime dataset) and active participation (the periodic e-mails that you have been sending me). They account for 40% of the final grade. The remaining 60% will be determined by the final exam:

In this link you can download the Campus Crime case. I added a summary of my personal solution at the end of the document. Once again, if something looks wrong please tell me and I will revise the case.

The final exam will take place next tuesday, June 5th. It will be similar to previous tests except that:

• It will include 20 questions instead of 10
• As in short tests, there will be three alternatives to answer each question and an additional "blank" option. On the other hand the grading policy will be more strict, that is: 
• a correct answer adds 2 points to the final grade, while
• an incorrect one subtracts 1 point, and
• a blank answer does not add or subtract, so
• the final grade will be the total of points obtained divided by 4

The criterion behind this policy is that the expected grade for someone who answers at random should be zero points. Be aware that the penalty for a wrong answer is therefore thougher than the one I applied in the short tests, so you should very careful when choosing an option.

Econometrics: Test #2

As planned, in May 31th you did the second short test. It consisted in solving the questions in the following test (correct answers in the last page).

The results, as well as the final grade for the test exam component, are the following:

The final grade has been computed as the highest grade from the first and second test, increased by a 20% if both were higher than 5 points. If something looks wrong please tell me and I will revise the case.

By next monday, June 4th, I expect to publish the grades corresponding to partial exams (those in the upper list), individual work (the Campus Crime case) and Active participation (from the e-mails that you have been sending to me). If anyone did not send me the Campus Crime case yet, please do it!

The "B" plan

Dear students,

As you may know, last monday 14th I suffered a coronary event that required hospitalization. Obviously, this will have an impact on our teaching and evaluation plan, so it is time to define a "B" plan.

First of all, from wednesday 23th onwards Professor Teo Pérez-Amaral will substitute me. You should go to classroom N-102 of Pabellón Prefabricado (Building nº 1).

Teo teaches the english group in Economics and we share our teaching material, so the transition should be easy.

Second, I promised you that I would prepare some test-type questions chosen from the Econometrics exams of 2000 Plan. You can download them through the following links: Lessons 1-4 and Lesson 5 onwards.

These questions are written in Spanish (sorry!) the right choice is marked and there is a short explanation in my awful handwritting (sorry again!). Be also aware that these questions offer four possible choices, while your exam will offer only three choices.

Third, next May 30th we were going to do a graded practical case in the classroom. Now it will be non-presential. Please download this MS-Word document (I updated the file on May 30th to correct a minor typo). It contains all the data and indications required. You should write your own analysis, according to the instructions, and send it to trabajoeconometria@gmail.com before May 31th. You are free to consult with each other: I am you to write and understand completely the analysis and its conclusiones.

Fourth, we scheduled a second test exam. It will cover Lessons 1 to 6. I will prepare the questions and Teo will supervise it. It has been scheduled for next May 31th.

Last, I am allowing comments to this post. If you use these comments to ask your doubts, my answers will be available to everyone.

I am very sorry for these inconveniences and will do my best to minimize them.

Econometrics: Test #1

As planned, in April 25th we did the "dry run for the final exam". It consisted in solving the questions in the following test (correct answers in the last page).

The results are published both, in the Econometrics tab and in this post (click here to download the spreadsheet). This document is encripted with the password that I gave you in class. I will keep updating  it as I collect new grades.

As I told you in class, 40% of the final grade will be decided on the basis of:

• Two test exams (the second one will take place in the regular class of May 31th)
• A practical exam, that will be done in the seminar of May 30th
• The bi-weekly e-mails, that you have been sending me so irregularly up to now

The grade resulting from the test exams will be the higher of both one plus an incentive, that will be awarded if both grades are 5 or better in the standard spanish scale (from 0, lowest grade, to 10, highest grade).

Econometrics: week 11 (April 23-29th)

In weeks 7-9 we:

• Explained Lessons 4.1 and 4.2, and
• concluded the practical work with the Beauty and hprice1 datasets

A "dry run" for the final exam

As I announced in class, next April 25th we will do a "dry run" for the final exam. It will consist in a short test with 10 questions about Lessons 1-3.

Econometrics: weeks 7-10 (March 26th to April 22th)

In weeks 5-6 we:

• Explained Lesson 3.2 (Inference)
• Continued the work with Many least squares calculations done (almost) by hand and Weight vs. age for a sample of children
• In the March 21th seminar, we concluded the work with the CEO compensation dataset

Econometrics: weeks 5-6 (March 12th to 25th)

In weeks 3-4 we:

• Explained Lesson 3.1 (except for the last slide) 
• Worked with Gretl, using mainly the datasets: Weight vs. age for a sample of children and CEO compensation
• Illustrated the practical computation of main OLS results using the example: Many least squares calculations done (almost) by hand

Econometrics: weeks 3-4 (February 27th to March 11th)

In weeks 1-2 we:

• Explained Lessons 1-2 and started Lesson 3.1
• Provided an introduction to Gretl, using mainly the dataset: Simulated data 

The goals for weeks 3-4 are:

• Explaining Lessons 3.1 (Estimation) and 3.2 (Inference) at least partially. If you already downloaded the Estimation lesson, please update it, as I changed a few things
• Reviewing the practical materials Many least squares calculations done (almost) by hand and Weight vs. age for a sample of children
• In the March 7th seminar, we will revise and make further progress with the homework defined below. Mainly that related with the CEO compensation dataset

Warning about March 1st class

Next Thursday, March 1st, I will not be able to attend the class due to an institutional obligation. We will recover the time lost using the second hours of the seminar.

Warning about the seminar

Next Wednesday, March 7th, from 12,00h to 13,30h (to compensate for the class lost) we will have the second seminar. We will have this seminar and all subsequent ones at classroom # 218. Please bring your computer if you can.

Econometrics: weeks 1-2 (February 13th to 26th)

The general idea of this blog is described (in spanish) in Acerca de este Blog.

The goals for these two weeks are:

• Explaining Lessons 1 (Introduction to Econometrics) and 2 (Simple linear regression: graphical analysis)
• Doing some practical work with GRETL and the dataset simulated data in the first Seminar (February 22th)

Warning about the Seminar

Next Wednesday, February 22th, at 12,00h, we will have the first seminar. According to plan, it was to be held at Computer Room #1.

As you know, the computers in this room are quite obsolete. On the other hand, many of you have laptops. If you are willing to bring your own computer, we could have the seminar in the classroom.

We will discuss and decide about this option in the next class.


Warning about March 1st class

Next Thursday, March 1st, I will not be able to attend the class due to an institutional obligation. We will recover the time lost using the second hours of the seminar.
