Historic Logging vs GDP in the Brazilian Amazon
Group 2
Quick Introduction
Objective: Apply the mathematical and coding techniques developed in the EPPS Math & Coding Camp - Fall 2025 to a real use case
Method: Data collection from official websites, visual and regression analyses
Problem: Are logging rates in the Brazilian Amazon correlated with the GDP of the Brazilian states that it covers?
Quick Introduction
Results:
The state of Amazonas has the highest nominal logging rates as compared to other northern Brazilian states
The state yearly GDP is highly correlated to the logging rates
The logging rates can be reasonably estimated using a simple linear regression model
