Statistical face validity refers to the superficial appearance that a measure or model seems to be a reasonable assessment of the construct it purports to measure. In quantitative finance, this means that an indicator or strategy intuitively makes sense to domain experts. While not a rigorous statistical measure, it is an important initial filter for credibility and practical acceptance. A model lacking face validity may face skepticism regardless of its statistical rigor.
Intuition
The intuition behind face validity stems from an expert’s accumulated knowledge and experience within financial markets. For instance, a simple moving average crossover strategy for cryptocurrency trading might possess face validity because its logic is easily understood and aligns with basic technical analysis principles. An options pricing model that yields obviously absurd valuations would lack face validity. This initial intuitive check provides a quick assessment of plausibility.
Assessment
Assessment of statistical face validity is primarily subjective, relying on the judgment of experienced traders, analysts, or portfolio managers. They evaluate whether the model’s inputs, outputs, and underlying logic appear sensible and relevant to the financial problem at hand. While not a substitute for empirical validation, a strong face validity can facilitate adoption and trust in new quantitative tools. It bridges the gap between complex models and practical market understanding.
