EDIT: I CHANGED THE SERVICE PROVIDER FOR THE BLOG AND THE CODE BLOCK BELOW GOT MESSED UP. ALL SLASHES WERE GONE. I TRIED TO FIX IT MANUALLY. BEWARE I did my proposal yesterday and it went well 😀 I used beamer to prepare my slide deck and was very pleased with how easy it was…
I was pleasantly surprised to find out that Arizona State University was a member of AWS educate, more so since my year of free trial ran out last month and I just payed my first bill for the Amazon instance I use for data collection. Amazon Web Services provides an easy to deploy, easy to…
I use markdown in my analysis reports and for my research log. When I was thinking of putting up a more official looking public profile page, I found myself thinking of using markdown to create my profile page on ASU web site. While Markdown is convenient in generating HTML, it is not really suited for…
PLM package is pretty decent for traditional econometric models, yet when it comes to datasets I have to deal with everyday it can be pretty inefficient. If only we had a version of within transformation that would work with multiple clustering variables… Actually, we have it in the form of felm package for R from…
For one of my projects I am using Python scripts to scrape web pages. Unfortunately, the dates in the pages are not in a consistent format. Some are like Jun 19 2014, whereas others are 28-Mar-14, yet others are 2010-Sep-20. The trickiest ones are the ones like Jun-10. Thanks to plannapus in stack overflow I…
I have been using Linux as my main system for years. One thing I have always felt the lack of was the Word’s grammar checking facilities. Especially when writing in LaTeX, I have often felt the lack of an automated system to catch the most common errors. Thanks to John Horton from MIT, now we…
Today I was faced with an interesting challenge, finding time zones for users defined by latitude and longitude. Thanks to extensive package libraries of R, the solution was not hard at all.
I am not much of a SAS person, I feel more comfortable in R. Yet there is one area where I feel SAS excels: experimental design, especially discrete choice experiments. Now to be honest, Aizaki 2012, also presents some basic guidelines in choice experiment design but the macros are nowhere near as elegant or as…
Theorizing that Newton’s theory of gravity holds for IT, and testing it by dropping a PC from an office window in the MIS department is obviously not valuable. March and Smith, 1995
From time to time I need to use SAS for some piece of analysis. Unfortunately installing SAS requires some workarounds these days. Here is my note to self on trickier parts of SAS installation. 1- Switch to bash instead of dash 2- Install dependencies
I use Wireshark in my demonstrations for the CIS-430 Networking and Distributed Systems class. I always enjoy the reaction of students when I sniff their FTP passwords off the air. To be able to gather packets in promiscuous mode how ever requires some authorization changes. Here is how I did it the last time I…
Through our discussions with the PhD students in the department, the lack of a replication journal has always been something we felt the lack of. Everybody agreed that scientific progress required replicability of results but, no one was able to spare the time to an endeavour which would surely go unrewarded. Now that there is…
