Example.Data

<code>Example.Data</code> is a hypothetical dataset constructed to demonstrate some of the functions in the package. Data are provided for a hypothetical experiment in which a stimulus is provided under different experimental conditions. The outcome is a normally distributed variable. The entire experiment is repeated multiple times (cycle) in each patient.

In clinical practice and research settings in medicine and the behavioral sciences, it is often of interest to quantify the correlation of a continuous endpoint that was repeatedly measured (e.g., test-retest correlations, ICC, etc.). This package allows for estimating these correlations based on mixed-effects models. Part of this software has been developed using funding provided from the European Union's 7th Framework Programme for research, technological development and demonstration under Grant Agreement no 602552.
