## Type I Error

A Type I error, often referred to as a false positive, occurs when a researcher rejects a true null hypothesis. In financial trading, this is a dangerous error because it leads a trader to believe they have discovered a profitable market anomaly when, in reality, none exists.

This can result in the deployment of capital into a flawed strategy that is destined to lose money. For example, if a backtest suggests a strategy has an edge based on a Type I error, the trader might over-leverage their position.

Minimizing Type I errors is a primary goal of rigorous quantitative analysis and backtesting protocols. It requires setting stringent thresholds for statistical significance.

Failure to control for this error can lead to significant financial losses and erosion of capital.
