mgcvUI

An Interactive Interface for the mgcv (Generalized Additive Models) Package

Abstract

mgcvUI is a graphical user interface for the R mgcv package, which fits Generalized Additive Models (GAMs) using penalized regression splines with automatic smoothness selection.

It offers three purpose modes—general predictive modeling, real-estate appraisal, and market-area analysis—and guides the user through data import, smooth-term specification, model fitting, diagnostic and effect plots, and downloadable reports. This article documents mgcvUI’s data-format requirements, modeling workflow, output displays, and complete feature reference.
