Conditional Visualization for Statistical Models: An Introduction to the condvis Package in R

TL;DR

The condvis package in R provides interactive visualization tools for interpreting complex statistical models by displaying data sections, fitted models, and observed data proximity, aiding model understanding.

Contribution

This paper introduces the condvis package, a new tool for visualizing and interpreting complex statistical models interactively in R.

Findings

Enables interactive visualization of data sections and models

Helps interpret complex models with observed data support

Provides a user-friendly R package for model visualization

Abstract

The condvis package is for interactive visualization of sections in data space, showing fitted models on the section, and observed data near the section. The primary goal is the interpretation of complex models, and showing how the observed data support the fitted model.
