The purpose of this work is to evaluate and compare various regression techniques—specifically Ordinary Least Squares (OLS), Weighted Least Squares (WLS), and Weighted Line of Organic Correlation (WLOC)—in the context of building airtightness measurements as prescribed by ISO 9972. The goal is to improve the accuracy...
