Structural Break Testing

Methodology

Structural break testing serves as a quantitative diagnostic framework designed to identify statistically significant shifts in the underlying parameters of a financial time series. By isolating points where mean reversion properties, variance, or covariance structures change, analysts can distinguish between stochastic noise and fundamental regime transitions within high-volatility cryptocurrency markets. This diagnostic process is essential for maintaining the integrity of predictive models that otherwise assume stationarity in asset return distributions.
