Welcome. Glad you are here. I am Álvaro a third year PhD student at the Research Centre for Operations Research and Statistics (ORSTAT) at KU Leuven I run this website as a way to collect what I have been learning lately. Most of my posts are difficulties that I encountered on my way and things that I genuinely consider relevant. I document them here primarily as ‘knowledge-bunker’ for my own but feel free to take a look if you want.
I work mostly with discrete choice models using stated preference data. I also developed a Stata package called -randregret- that fits Random Regret Minimization models. Some slides about it are available if you are interested. Additionally, I maintain a data-bank called TheDiscreteChoiceDataBank which contains discrete choice data. If you want to add your own data, please send me an email and I’ll be more than happy to add it.
Lately, I gave a small talk about computing numerical derivatives using Mata at the StataConference2021. If you are interested, you can find the source code here.
Away from my keyboard, I enjoy doing bodyweight exercises and trying out new plant-based restaurants on my way :P.
Finally, feel free to follow me on Twitter or GitHub :)
