Understanding the Impact of Scaling Independent Variables on Regression Models with the `betareg` Function in R for Binary Outcomes Using `sjPlot`.
The provided code and explanations help to clarify the use of the betareg function in R for modeling binary outcomes, specifically in relation to the sjPlot package. Here are some key points from the explanation: Scaling Independent Variables: The original model has a problem with uncertainty due to all values being very low. Scaling the independent variable can help improve interpretability by reducing the impact of extreme values. Model Transformations: The sjPlot package typically transforms values on the log scale using the exp() function, which affects the output of functions like tab_model().
