Null Hypothesis Significance Testing

Null hypothesis significance testing is a formal procedure for deciding whether a result is statistically significant or merely the result of random chance. In structural break detection, the null hypothesis typically assumes that no break exists and the model parameters are stable over time.

If the test statistic exceeds a critical value, the null hypothesis is rejected, suggesting that a structural break has occurred. This process provides a disciplined framework for making data-driven decisions in trading and risk management.

It ensures that traders do not react to noise or minor fluctuations, but only to statistically significant changes in market dynamics. It is the gatekeeper of quantitative research, requiring evidence before a model is altered.

By setting clear thresholds, it helps maintain consistency in how market signals are interpreted and acted upon.
