%description
The empirical cumulative average deviation function introduced by the
author is utilized to develop both Ad- and Ud-plots. The Ad-plot can
identify symmetry, skewness, and outliers of the data distribution,
including anomalies. The Ud-plot created by slightly modifying Ad-plot is
exceptional in assessing normality, outperforming normal QQ-plot, normal
PP-plot, and their derivations. The d-value that quantifies the degree of
proximity between the Ud-plot and the graph of the estimated normal
density function helps guide to make decisions on confirmation of
normality. Full description of this methodology can be found in the
article by Wijesuriya (2025) <doi:10.1080/03610926.2024.2440583>.
