%description
In repeated measures studies with extreme large or small values it is
common that the subjects measurements on average are closer to the mean of
the basic population. Interpreting possible changes in the mean in such
situations can lead to biased results since the values were not randomly
selected, they come from truncated sampling. This method allows to
estimate the range of means where treatment effects are likely to occur
when regression toward the mean is present. Ostermann, T., Willich, Stefan
N. & Luedtke, Rainer. (2008). Regression toward the mean - a detection
method for unknown population mean based on Mee and Chua's algorithm. BMC

Acknowledgments: We would like to acknowledge "Lena Roth" and "Nico
Steckhan" for the package's initial updates (Q3 2024) and continued
supervision and guidance. Both have contributed to discussing and
integrating these methods into the package, ensuring they are up-to-date
and contextually relevant.
