• Developed STATA code to extract full sample from airline dataset
• Tested full sample on EC2 instance r3.2xlarge (memory-optimzed, 61GB RAM)
• Simulation consumed full 61GB RAM and failed
• Andrew diagnosed that my input matrices were dense, and that I could save RAM by making them sparse
• Searched for R packages that would run desired statistical estimation techniques using sparse matrices as inputs
• Found diverse packages capable of computing desired estimation techniques using sparse matrices as inputs
• (In process) Revising R code to utilize these packages
