This project contains elaborate examples of common statistical models using simulated data from hypothetical studies. Each markdown simulates, visualizes, and models the data. These steps are followed by an easily-understandable interpretation of the results in terms of the study.
I started writing these markdowns to demonstrate how different models can be used to test hypotheses
