New Features

• Implemented Lilliefors correction for Kolmogorov-Smirnov normality tests in both normality() and summary_table() functions. The Lilliefors test provides more accurate p-values when distribution parameters are estimated from sample data.

Improvements

• Added methodological references: Lilliefors (1967) and Dallal & Wilkinson (1986)
• Updated documentation to clarify that K-S option now uses Lilliefors correction

Dependencies
