Statistical Power
Statistical power is the probability that a test will correctly reject a false null hypothesis, effectively identifying a true effect when it exists. High statistical power is essential in derivative trading to ensure that subtle signals in noisy market data are not missed.
If a test has low power, a trader may fail to detect a profitable market inefficiency, leading to missed opportunities. Power is influenced by the sample size, the significance level, and the true size of the effect.
By maximizing power, quantitative researchers can build more sensitive systems that respond effectively to changing market conditions. It is the measure of a test's ability to avoid Type II errors.
