This report evaluates whether retailers should prioritise temporary price cuts or increased media spend to drive growth. Using a shock-based Marketing Mix Model (MMM) applied to apparel retail data (2019–2024), price and spend innovations are residualised to remove multicollinearity, yielding stable short-horizon elasticities. Results show that discounts dominate for unit growth, while media spend dominates for revenue growth. Scenario formulas and an optimiser are provided for practical planning.

This webpage aims to make the foundational principles of Data Science more accessible to non-statisticians. Many definitions and examples are based on the book "Fundamentals of Probability with Stochastic Processes" that I studied during my Bachelor Econometrics & Operations Research.
