As the owner of BBQ2GO, I want to evaluate the effectiveness of advertising expenditures across three channels: social media, direct mail, and newspapers. Using Multiple Linear Regression (MLR), I aim to quantify the impact of each advertising medium on sales, identify areas for budget optimization, and address potential issues like multicollinearity. By leveraging R for data analysis, I develop a reproducible framework that integrates data cleaning, model fitting, and advanced metrics. This analysis provides actionable insights into advertising strategies while highlighting the utility of MLR in business decision-making.

Unlike traditional methods that rely on extensive observation periods, I was determined to develop a technique to estimate parameters accurately within short observation intervals.
