To make the replication as easy as possible for other members of the research community, we created a VM that contains all of the data, the R project and the packages required to run our experiments. We also provide a README file to detail the steps required to run the scripts and re-produce our results.

A copy of the VM can be downloaded from the following link.

To run the VM, you will need to install the VM player, which can be downloaded from the following link.

To log into the operating system installed on the VM, please use the
following credentials:

Username: hid
Password: fse2011

In case some you may already have R installed and would like to run the scripts on your own environment, the data and the scripts can be downloaded from this link. This folder also includes the README file.
