A Sigma Xi poster on work by Jose-Antonio Espin-Sanchez, Salvador Gil-Giraldo, Daniel Giraldo-Paez, and Chris Vickers. I assisted by building the Floridablanca census and constructing preliminary figures and charts. I am no longer working on this project.

This Sigma Xi poster presented a preliminary overview of socioeconomic statuses in Spain during the 18th century, prior to NSF Grant Submission. The main idea is to build family trees and track changes in social status or wealth, using signifiers, such as “Don”, occupation, and incomes. The preliminary data analysis comes from two historical censuses: the Ensenada (1754) and Floridablanca (1786) Censuses. In our analysis, we observe income, household size, occupation of parents and guardians, social status, and age, all manually inputed from the historical censuses.

As a sidebar, this was also my first exposure to economic research.

How much does the NBA Summer League matter to players? (joint with Shivram Vishwanathan)

Many do not pay attention to the summer league in years past, but as more and more one-and-done NBA prospects enter the league, the coverage of the NBA summer league has gone up. We were curious to see how the NBA Summer League contributes to the development of young NBA prospects in their rookie seasons. While our observed effects may not be causal, we hope to shed some light in how useful the NBA Summer League is for the player and how closely we should follow during the offseason.*

I had a cousin ask me about why Asian housing prices are so much higher than western housing prices (like in New York). Currently in my life, owning real estate does not seem so feasible, so naturally, I have no idea what these prices looked like other than being way above my pay grade. That being said, I investigated the time series prices of housing (more specifically growth of property prices) in New York vs those in China. Furthermore, the higher prices of property observed in China, also extends to Hong Kong.

It has been two months into my new job at the Federal Reserve Bank of New York (FRBNY). As a research analyst (RA), I primarily assist economists with creating paper figures and tables, running regressions, and cleaning data.1 It is common knowledge that many RAs move on to pursue a PhD since, in most cases, the RA job is meant to prepare for the things one is expected to do in a PhD program. I pose the following questions:

Markov Chain Monte Carlo and the AUDL Project: Reflections

For my mathematics senior capstone project, I examine the robustness of a Poisson Goal-scoring model proposed by Everson and Goldsmith-Pinkham (2008). My expository capstone paper is found here. The purpose of this paper is to highlight the goal-scoring model, simplify it, and apply it to a similar scenario. In this blog post, I go back and examine the failure of prediction in my simplified Markov Chain Monte Carlo (MCMC) algorithm. I will go look at two division in particular: the Midwest and West divisions.
