Econometrics (1 º Sem 2020/2021)

The vídeo file of lecture 7 was posted in the website of the module. This corresponds to the file Heteroskedasticity_part2.zip (Heteroskedasticity_part2.mp4)

The video file is in mp4 format and is zipped and therefore students will need to unzip it to a suitable folder.  If you do not have the software Winzip to unzip the file, I suggest that you use the software 7-zip which is freeware.

Notice that the unzipped file of the vídeo is also available in Microsoft TEAMS in the team of the module Econometrics.

The slides of the lecture correspond to the file Heteroskedasticity_part2.pdf.

The students should read the following pages of Wooldridge (2013)’s book: 275 to 294.

The homework of this week correspond to the following exercises of Wooldridge (2013)’s book: 1, 2, 4, 8, C6 of Chapter 7
