biostats 1.1.2
Bug fixes
sample_size(): corrected dropout adjustment from
approximate formula n * (1 + dropout) to exact formula
n / (1 - dropout), preventing underpowered enrollment at
higher dropout rates.
biostats 1.1.1
Improvements
- Minor change to sample_size function for better readability.
biostats 1.1.0
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
- Enhanced p-value formatting to display “p < 0.001” instead of “p
= < 0.001”
- Added methodological references: Lilliefors (1967) and Dallal &
Wilkinson (1986)
- Updated documentation to clarify that K-S option now uses Lilliefors
correction
Dependencies
- Added
nortest package to Imports
