Economic Significance
Meaning ⎊ Assessing if a trading edge is large enough to generate actual profit after accounting for all market costs.
Null Hypothesis Significance Testing
Meaning ⎊ A formal method for making statistical inferences by comparing observed data against a null hypothesis of no effect.
Type II Error
Meaning ⎊ The failure to reject a false null hypothesis, resulting in a missed opportunity to identify a valid market edge.
Sample Size Sensitivity
Meaning ⎊ The impact of data quantity on the stability and statistical significance of financial model results.
