gwbr - Local and Global Beta Regression
Fit a regression model for when the response variable is
presented as a ratio or proportion. This adjustment can occur
globally, with the same estimate for the entire study space, or
locally, where a beta regression model is fitted for each
region, considering only influential locations for that area.
