Pilot Matching

Authors: Rocky Aikens, Dylan Greaves, Michael Baiocchi

This repository contains the code and data used to write an upcoming paper: "Using the Prognostic score to Reduce Heterogeneity in Observational Studies." The preprint is available on Arxiv.org (statistics methodology).

Contents of this repo

• Analyses - all vizualizations, interpretations, and analysis of simulated data are in .Rmd files here. The most important files are Main_Figures.Rmd, which makes all of the main figures for the manuscript and Supplementary_Figures.Rmd, which contains all the supplementary figures.
• Code - all code (R and bash) to run the simulations is here.
• Data - all data produced from simulations is here.
• Figures - current versions of all figures are here. These figures are automatically produced from the code in analyses/Main_Figures.Rmd

Code and Data each contain a README further explaining the contents of that subdirectory.

Other note: AWS

Much of the computational heavylifting to produce these simulations was done on an Amazon Web Server EC2 instance. There are two EC2 instances which I have made for this project: Rocky-Buffalo and Rocky-2Buffalo. On each of these instances, a standard batch of 1000 simulations can take 6-24 hours, depending on the sample size and specific simulation parameters. Pairmatching tends to take longer, Fullmatching tends to be faster.
