Workshop 1: script-writing

  • See my econometrics notes below for a refresher on R, R Notebooks, and for an intro econometrics refresher.
  • R: fixest for running regressions (as opposed to lm or plm)
    • faster estimation
    • flexible formula writing allows simultaneous estimation of many similar regression models, much simpler and more convenient inclusion of leads, lags, and differences of variables, and intuitive specification of standard errors
    • its etable function provides a nice pipeline for creating very customizable tables automatically (better in my opinion than the usual suggestion, which is the stargazer package)
  • R: magrittr for piping for very intuitive and readable script-writing especially for data processing. An intro here .
  • Stata: an intro to data cleaning functions

Workshop 2: project-oriented workflows



Additional topics

Topics I’d cover with more time

  • Debugging tips: how to identify bugs in your code
  • Using ChatGPT as a coding resource. Error prone but really valuable if you ask questions well. It also generates reproducible examples if you ask. Some things I use it for:
    • “How do I do [task] in Stata?”
    • “How do I implement [task] in R using [package, e.g. the tidyverse]?”
    • Copy and paste a chunk of code and then ask what each line is doing
    • [pasted code] What’s a more efficient way of accomplishing the same thing?"
    • “This is my code: [pasted code]. I get an error that says . Where is my mistake?”
  • Writing your own functions
  • Implementing different kinds of regressions (I do this a little bit in my econometrics notes)
  • Customizing regression tables
  • Data visualization
    • R: see the ggplot2 cheatsheet
    • Stata: see the commands in the cheatsheet and here ’s a guided introduction

Other possibly helpful research resources:

  • Trello for keeping notes, maintaining to-do lists, storing relevant documents, summarizing research meetings, etc. Sychronizes across all devices.
  • How to present an applied micro paper
  • Browser extensions
    • EZProxy Redirect to access online resources that Columbia has subscriptions to when away from university internet and without using a VPN
    • Simple Mass Downloader to download all files contained in a web page
  • Literature review
    • Google Scholar search is obvious but also click on the “Cited by” link under a search result to find other relevant and possibly more up to date papers and methods or see if someone’s already done what you want to do
