Confidence Interval Calculation in Q-Q Plot Analysis is a methodological framework within statistical inference that quantifies uncertainty regarding percentile matching between empirical and theoretical distributions. The core principle involves deriving asymptotic variances for order statistics to construct bounds around the expected ranks, thereby testing the validity of distributional assumptions without relying solely on point estimates. This concept operates strictly within the domain of Quantitative Statistics as a subfield of goodness-of-fit analysis, utilizing formal definitions of quantile functions and covariance matrices under specific regularity conditions.
