Model Drift Quantification

Measurement

Model drift quantification serves as the analytical assessment of the performance decay occurring when the statistical properties of live cryptocurrency market data diverge from the assumptions embedded during the training of pricing or risk models. By systematically evaluating the residuals between predicted option prices and realized market values, practitioners identify the precise moment when the underlying volatility surface or liquidity profile renders a model obsolete. This essential surveillance prevents the accumulation of latent errors that typically arise from the non-stationary nature of digital asset returns.
