Demand Modeling & Market Estimation
Our market estimation framework employs a robust combination of top-down and bottom-up approaches, further reinforced by multi-level data triangulation to ensure precision and reliability. This layered methodology allows us to validate market size and forecasts from multiple perspectives.
Bottom-Up Approach: This involves segmenting the market at its granular level, calculating the size of each segment, and aggregating them to derive the total market. For the GERD therapeutics market, this includes:
- Diagnosed Prevalence of GERD (by country/region)
- Prescription Volume and OTC Unit Sales for specific GERD therapeutics (e.g., PPIs, H2RAs, Antacids)
- Average Selling Price (ASP) per unit/dose for each therapeutic class, accounting for branded vs. generic.
- Patient Adherence Rates to long-term GERD treatment.
Top-Down Approach: This method begins with a broader market estimate and then drills down into specific segments based on defined parameters (e.g., application, type, region). This ensures that our segment-level estimates align logically with the overarching market context.
Multi-Level Data Triangulation: This critical step involves cross-validating data points obtained from primary research with secondary data, and vice-versa. It also includes comparing findings from different primary sources and different secondary sources to identify discrepancies and refine estimates, thereby enhancing the overall accuracy of our projections. Statistical modeling techniques, including regression analysis and cohort analysis, are applied to forecast market growth based on historical trends, economic indicators, demographic shifts, and anticipated regulatory changes.
