Hi all,
My qestion is about dependence across observation. In our replication assignment, the
authors disaggregated a dependent variable into several dependent variables. That type of
coding does make sense in their case. Furthermore, these newly formed dependent variables
are mutually correlated. For that reason the authors accounted for the correlations among
the newly formed dependent variables by using clustered standard errors. However, the
authors did not account for those correlations among observed dependent variables in their
model (probit). If that was not the typical way to apply probit model to data analysis, I
would consider that an inappropriate use of MLE. Concerning possible solutions, we could
account for the correlation among observed dependent variables in different. Two solutions
that come to mind are group correlated binary variables with an extended beta-binomial
distribution, or ordered probit. Is there anything more appropriate than that? I will
appreciate your help.

Dear all,
Does anyone have experience downloading R on Ubuntu? I'm having
trouble doing this, even after working through the instructions here:
http://cran.r-project.org/bin/linux/ubuntu/
Many thanks,
Shelby

Hi Shelby,
I run R on Ubuntu.
This is the relevant line from my /etc/apt/sources.list file.
"deb
http://software.rc.fas.harvard.edu/mirrors/R/bin/linux/ubuntu karmic/"
Depending on your version, you may need to change the "karmic".
Once you add that line. Run "sudo apt-get update" or run the synaptic
package manager. Then you can install r-base.

Hi folks,
We made this announcement in section, but in case you weren't around --
there will NOT be a problem set going out this evening or anything due next
Thursday. Instead, we're adding a small assignment onto your replication by
asking you to create a replication data set in the IQSS dataverse (and then
to include a citation to this replication data set in your paper).
We'll be discussing this in lecture on Monday.
best,
Maya
