In 2016, I signed a petition in the hopes that our voices as academics would bring peace to my country. The Turkish government labeled me and the other signatories as traitors and have been working hard to quash our voices.
I keep talking about using large datasets and how some models take quite long time to run. One of those models is typically two way fixed effects models. While regular econometrics packages like plm are quite good for reasonably large datasets, more and more I find it hard to use with my datasets. Here is…
I am doing a discrete choice experiment design for a project that we are just starting. The idea is to present screenshots of various app’s in an app store and ask the participants to pick one. For this, we need screenshots of app’s with key variables changed. The problem is that, unless you are careful…
My older daughter is old enough to play simple games (Animal upon Animal, Brandon the Brave) but dice throwing has been a problem. A while back I decided to build a dice tower with the dual purpose of both playing games with kids and to make sure the dice is properly random (no cheating).
In Hawaii for HICSS 50. So far so good. Have seen old friends, met new friends and am enjoying Panoply security competition. Paper being nominated as best paper does not hurt either.
I use AWS to run the various scripts used in data collection. I have been paying about $20 each month for a t1 micro instance since my free tier and academic credits ran out. That is quite a price to pay for 1 core and about 600MB ram. Maybe AWS is not the best option…
I often use data from various sources and sometimes have to get creative about transforming the data into a format that I can use easily. So far I have done this mainly with R (and with Python from time to time). The other day, Dr. Mazzolla pointed to OpenRefine, an application for data clean-up and…
I will be presenting our paper, “Surviving and Thriving in Online Labor Markets” this weekend at WISE 2015. Our study aims to uncover the dynamics shaping the online labor markets (freelancer.com, upwork.com, elance.com …), with a focus on the role of country development level on the IT service providers’ ability to survive and earn a…
I am currently developing a tutorial for EMBA students for IBM’s Watson Explorer. Having just recently finished content development for R workshop for MSBA, I must say it is a pretty interesting experience. On the one hand you have R, a complex but powerful tool that is designed to lift (almost) any kind of analytics…
I am preparing presentations for the upcoming R workshop. That means I have to find a way to integrate R code and results into my presentations. Now I know there are a number of ways to achieve this, but I like beamer for presentations and R for analysis. Now thanks to Knitr, I can bring…
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 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…
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…
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…
