GSoC 2019 - The EAPR Package

This gist provides a summary of my accomplishements during the development of the EAPR R package during GSoC 2019 as well as plans for future development. Please follow this link to the package for more detail on the package, including the motivation, guide for starting out, and how to contribute.

Goals

Our overarching goal for this summer was to get development of the EAPR package off the ground and running. This objective was accomplished as methods for data extraction from the Wharton Research Data Services (WRDS) database, Fama MacBeth regressions, and quantile portfolio creation were implemented during this period. Completing these methods is an important step towards supporting reproducible research in the empirical asset pricing subfield of financial research.

Challenges

Naturally, there will be some challenges when doing something for the first time, and this was no exception for me. Throughout the development of my first R package, I had to learn about the Roxygen2 documentation system, properly manage dependencies, coding/debugging workflow, among other hurdles. Overall, my developing this package contributed greatly to the rounding out of my skillset as a coder.

What's Next

We will continue to develop this package to facilitate research in empirical asset pricing. In the short term, we will look to make improvements to the current methods to increase their efficiency. Additionally, we plan to add extraction of more granular data such as the daily CRSP datasets and quarterly company financials from Compustat. Other features will also be added in the future to cater to a greater breadth of interests and we are open to any ideas (Instructions for submitting feature requests are found in the README on our github site).
